Abandoned again - broken heart from this app

I’m just full of emotions right now. I feel like I just want to explode. I broke up with my ex a week ago he keeps texting me saying I love you I don’t respond because I don’t pay no mind. What’s bothering me is why did I let this dude use me and I trusted him. He manipulated and used me and I have serious trust issues I never tell anyone what I go through because it’s not safe at all. I feel like I don’t want to trust a guy ever again yes I’m 19 and I’m still young and should date but I don’t have the energy anymore. I attract terrible men that use me and I cave in to easy because I’m lonely and my life is miserable and even doing the things I used to like feel like a chore. I told my sister this today and she said I should be patient that the right man will come to me. But I feel like even if he did I would reject him because I’m an easy person to take advantage of.

I just got broken up with 13 days ago after 5 months super unexpectedly for no reason other then he needs to work on himself. That night i was really alone because my parents told me he was a good influence on me and my friends weren’t so i had no one. I added this guy on Snapchat that same night and we’ve texted and called every night since. We met 3 days ago and it went really good. We were both nervous but both talked about the next one and how we both had fun. Last night he went to bed without even a goodnight or any talking that whole day but apologized and said goodmorning this morning. Then tonight he randomly sends a paragraph saying he doesn’t think it’s going to work. When i asked why he said “Idk our personalities are just a bit different and idk if I’m really ready to be in a relationship”. It makes sense i guess but I’m really struggling with the fact that my last relationship said that exact same thing and i can’t help but think there has to be something wrong with me. I never cheated or did anything that could’ve upset either of them. I’m 17 and i really feel like i should just stop trying for a relationship but no one is giving me any kind of advice so I’ve just been over thinking all of it. Any past relationship I’ve gotten over by meeting someone new but I don’t know how to “work on myself”. I really think I have a fear of being alone. Please help!

Hello, this is my first day here. Ran across this app on social media. I hope you finish reading. Wanted to see if anyone was somewhere in my shoes that can possibly give me some advice. Ive been in a relationship with my partner for 6 going on 7 months, we will call them H for now. At first, everything was so prefect, laughs, conversations, so much affection. Recently caught H on a dating app 10 days after my birthday, on the 4month mark, and the app was hiding it in their hidden tab section on your iPhones. The conversations were all deleted except for one. That one conversation happened to be with one of my old friends that I fell out with because they were moving in a snake way. They reached out to me via social media and told me about H’s dating account. With me having the evidence, H was seeking out attention from other people while I was away at work. Asking to be best friends and asking for their social media information. When confronting H about the messages I had, they denied it being them claiming that it’s a fake page and they got those pictures off of H’s social accounts. H opened their phone to try and show me they didn’t have the app. When i seen the hidden tab I asked H to open it. H hesitated but proceeded to opening the tab. Boom. The dating app was in the tab with the “fake profile’s account and pictures” but the text messages were all gone. H agreed to delete the dating app and unfollow the accounts they asked for on their. H thennnn proceeded to try and negotiate to keep them on their account or they would delete social media in general. Of course that won’t sit right with me so we agreed to both be off social media. Everything got better until, H was using the restroom and was in there for a while so I went to the restroom and just talk with H. As I opened the door, H quickly swipes out the app and turns the phone off. I asked H to turn it back on and unlock it and open the hidden tab. The social medias we both agreed to get off of was in the hidden’s tab once again. Now my trust has completely been shattered but I still love H. However, my real point here is, I do think that H has damaged me and I don’t think I can’t trust them even tho H swears they won’t do it again. I do also feel like I am doing too much and putting my anger and frustration against H because of what they did. I am lost and confused and need some advice on what you would do?
