Avoidance vs boundaries

I read a lot of other people’s posts where they deal with intrusive feelings, and sometimes even emotions? Would anyone care to further explain so i can understand this better? it would be very much appreciated.

Does anyone have any advice for how to know the difference between ocd and real feelings/thoughts? Sometimes an intrusive thought will come in and I immediately know it’s ridiculous and I can just leave it alone and it won’t bother me but other times I really really don’t know. It’s when ocd hijacks and twists my real feelings and thoughts and tries to manipulate me into believing they’re something they’re not or something that doesn’t align with my true morals or intentions. But since it’s twisting and mixing with real feelings I get so confused and scared. Everything gets jumbled and I feel like I can’t trust myself or my own mind. Yet other times and other topics I can laugh off and push away just fine. Make it make sense. And then I start to think well maybe I don’t have ocd at all and I’m just in denial because I don’t want to accept that these scary/concerning things are true about myself. Or maybe that’s just the ocd talking.

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?
