I want my ROCD thoughts about love to stop so I can enjoy my relationship. Please help me I feel on my own with it.

something that really bugs me and gets in my head with my rocd is that for most of my relationship i’ve had this nagging anxiety and ocd about it. i can accept my thoughts for the most part, but have this underlying fear that this one could really mean something and that makes me feel guilty! i don’t want to loose her but my mind tells me i do because ive had these thoughts. it’s even coming up in my dreams now! i had a dream last night that i cheated and it made me panic all today and feel so bad and this thought came up again! any advice?

I’ve been struggling with relationship OCD and differentiating between what is an intrusive thought and what is a real doubt. I was really happy with my partner then I got one aggressive thought that I didn’t love him and this spiralled into noticing all his flaws. I struggle being around him because I feel a huge sense of guilt that these thoughts even come into my head and I cannot figure out if this is my brain lying to me or this is how I feel. It’s really impacting a relationship that is so important to me.

I'm 18, and been in a relationship with my man for nearly 2 years. I started living with him around 2 months ago, and all I do is think about if he's cheating. We were long distance for a year and a half of our relationship, maybe seeing eachother once every month or two. I decided to move in with him, and ever since all I can think about is if he's cheating or watching porn. When he's in another room I think he's doing something wrong, I have to check on him every ten minutes to ease my anxiety. I didn't have this problem before moving in. Granted he has talked to some girls on his phone, even having his ex on his phone (didn't do anything bad) and he is porn addicted though he is getting better for me. It's gotten so bad I want to leave him. A couple days ago I broke up with him and it absolutely broke my heart, I couldn't bare it so I gave him a month to show me he can do better, and for me to work on myself. If I'm still unhappy with us I'm going to leave. I love this boy more than anything. I'm scared to be without him, this is my first real relationship. At this point I refuse to even sleep until he is sleeping. I don't want to start over, I don't want to leave him, but I really can't take this pain it's causing me. It's all I think about. I've convinced myself so many times that he's cheating, but I know he wouldn't. I question whether it's anxiety or intuition. Maybe I just know deep down he really is cheating and I just don't want to believe it. I don't know. I don't think he would do that, but at the same time he's really into women. I hate that he looks at other girls in a sexual way, it bothers me so much, and we talk about it often, but with it being an addiction it's difficult. He has gotten a lot better since we have talked about it. He understands I have an issue and is usually happy to talk about it over and over and promise me over and over that he's not cheating. He allows me to have his phone whenever I want and everything, I have no reason to think he's cheating, but I can't get over it. It's not fair to him either. How do I deal with this? How do I stop hurting so much?
