Really struggle to understand why this happened to me in the middle of such a good relationship.

Longer post, but please, I need some guidance. I thought that my thoughts relating to relationship OCD were taking over. But, my bf started treating me differently. I tried to have a conversation and communicate this worry. He then texted me that he had actually been feeling distant for a month and has been meaning to tell me. But “we’re fine now.” I spiraled. Later in the week, he went quiet after a disagreement. After he promised we were okay and he was okay, I found later he was texting a mutual friend (female) that I was crying again. She said that it was fucking insane and other hurtful things about me. He said he lost his trust with me because I looked through his phone and saw that message even though during the whole relationship we had a mutual understanding that we had nothing to hide from each other and he always assured me that I could look through his phone at anytime. It’s ok for boundaries to change in a relationship, but it wasn’t communicated and I was harshly reprimanded. During the texting chain with the mutual friend he also said that “she just has no idea.” When I addressed this, he then said that for the past month, he actually felt he didn’t want to be in a relationship, but still loved me. I’m ruined. I had the same thoughts in January and knew I loved him. I found out it was ROCD (through this app) and told him the day after the realization because it was eating at me. So him saying I wouldn’t understand and telling other seems unjustified. I would’ve been the most understanding. Any help would be appreciated greatly.

I feel like I really need help right now. I keep reminiscing on my old relationship and comparing it to my current one. For context, within my old relationship I had been with him for a pretty awful year and 3 months. Within the first 3 months I realized that I didn't actually want to be with him, but I felt sorry for him. So, I stupidly started self sabotaging the relationship. I know that it was stupid, and I tried to break up with him but every time I felt bad. His mental health was already bad and I hate any possibility that I can make someone's mental health worse. That whole "relationship" was so toxic on both ends though. All of that alone has me so messed up. But with that I also had this false attraction to him. Like, I would always be figuring out what I wanted in a relationship and tried to do that with him despite knowing that I didn't actually want to be with him. Now my mind keeps trying to convince me that I'm doing that with my current relationship. I know that I'm not. This one feels genuine and it's pretty healthy. We have our bumps, but we both have this want to fix it and it's just so nice. I hate that my brain is trying to ruin this for me.

my name is isma, i am 19 in nyc. i met this amazing guy at the beginning of the year, we hit it off immediately and he really stood out to me. i recently broke up with him because i feel like if id put him thru a lot if he’d stay with me. i recently came out to my parents and it wasn’t voluntary. i was caught with him and then had to reveal that i was gay. my parents didn’t take it too well. i felt uncomfortable and a little scared to be at home for some days. that settled in a week and both my parents told me they were acceptant but in the end it just felt to me like if they accepted me but they just didn’t wanna know about it anymore in a sense of just avoiding touching on the topic. now me and my boyfriend, i was going thru a lot and he gave me all his attention and was there for me whenever i had to vent or just cry because of everything going on. it’s crazy to think that at 19 years old id be coming out to my parents when at the start of the year, i never thought that’d be something id end up doing. ive never been open about my emotions or a “soft” person because i was never able to be myself at home and with my parents. sometimes i can’t even hug anyone. i find it hard to speak to strangers that r not my friends. i’m very picky when it comes to making friends. i feel like my thoughts are all over the place and im very indecisive. i miss my boyfriend and i wanna go back with him but im scared that ill ruin things again. before him, i was stuck in hookup culture and thought that by hooking up w a guy i was interested in, he’d wanna stay with me and get to know me. i was used many times and ive also used people many times. i’ve been done dirty and ive done people dirty, i dont think of myself as a good person but i felt loved and deeply cared for by this guy. he lives in nj and i live in ny. sometimes he’d even surprise me at work and i cried the first time he did. i felt so special and in awe because i would’ve never thought i could get so emotional over a small gesture. to me it wasn’t a small gesture. it was everything because he came from all the way in nj to ny just to see me for a couple of minutes. i hate the way that i am. i am unconfident, i think i am so ugly, sometimes i question how he found me attractive to date. i overthink everything, i cried one time imagining him coming to see me in ny then having to go home so late back to nj, i dont think im worth it and i felt like i didn’t deserve that and maybe it’d be better if he found someone near him. i also compared myself a lot with him. he’s such a kind spirited person, he’s always smiling and i on the other hand get told i look sad or anxious. i am i pretty negative person and that just adds on to me being an overthinker. i always thought someone as happy as him deserves another happy person and not someone who gets mad or agitated easily. i wish i can be more for him, i do miss him a lot and i plan on talking with him again. i just wanna talk everything out, even if we don’t date for sometime, i wanna be around him and know we’re gonna get back there again someday. he’s the best person that’s came to my life, i know ppl may say to let it go and see it as a learning experience but i don’t wanna move on if it’s not me moving on by his side. i really do wanna be with him i just wanna get my head clear. i don’t know what to do, im stuck
