relationship thoughts

I'm struggling really hard with relationship obsessions. Do I really love my partner? How can I know? Am I really just faking it? That kind of thing. It's making my life and relationship a lot harder than they need to be. I could use a few helpful coping mechanisms, trying to move away from less helpful ones like chasing reassurance.

Does anyone else unintentionally self sabotage their relationships? I tend to seek so much reassurance that they get sick of me. I only seek reassurance because I get scared that they're going to leave me (have abandonment issues) and then it becomes a self fulfilling prophecy because I worried so much that it ends up happening. I get trust issues about my partner cheating because I imagine worst case scenarios all the time and it really strains all of my relationships. Anyone else do this? What have you done to help?

I’ve been really struggling the last week and I need some help. I’ve been seeing a guy for about 2 months who checks a lot of my relationship boxes. He’s so kind and we have a lot of fun together. The first few weeks I was totally smitten but had moments of fear about being committed. We talked about it and decided to take things slowly, and then I would have days of feeling like every thing was perfect with some fearful feelings in between. Two weeks ago now my SO-OCD and ROCD started to come back a little as well as my more anxious-avoidant behaviors. I started to get more scared of the future and it was more intense. At the end of last week, he asked me to be his girlfriend and I said yes. He is exactly the type of person I see myself marrying and has great values and is so secure about me. Until last week, he generally made me feel so safe and secure. Ever since saying yes, I feel so scared and anxious and my SO-OCD and ROCD is on max. I also find myself getting more annoyed and irritated about things that were minor annoyances or non-issues before. I’m having intense physical responses to both OCD themes, and the nagging thought and feeling that I need to end things with him because we aren’t right for each other. It makes me feel so sad and guilty. Sex is becoming harder because of the thoughts too, whereas at first it was perfect. I don’t know who I can talk to about this without them telling me to just break up with him. Everything is so new so I think they’d chalk it up to my intuition. But I do want to be in love and have less fear around relationships, so I don’t want to give into the fear. I think it could help me to set boundaries and have space for myself more often. I think I need some advice or insight. I know I shouldn’t ask for reassurance, but having some around how other people have felt at the beginning of a relationship would help. Why is it that the label is freaking me out so much? How do you guys set boundaries to prioritize yourself when you feel this way?
