Hot flash anxiety

So I have been working with exposure therapy for the past couple days and I think it's going good. But I have a question for those that suffer from relationship OCD. Now the thought "I don't love him" isn't about my husband... I'm gonna feel terrible for saying this but it's about my own son. He's my only baby and he's 7. I know deep down I love him more than anything but small things trigger me and makes me think I don't. Like tonight I'm forgetting some good memories and some things I feel like good mothers would never forget. Is this common? I'm freaking out here.

I’ve been with my boyfriend for 3 years and he is an absolute angel. All throughout the relationship I would have nightmares and intrusive thoughts “what if he leaves/cheats”. And he would reassure me and treat me like the world revolves around me. Lately I’m realizing this was actually ocd and not anxiety as I had previously thought. I would get paranoid if he didn’t check his messages for a couple hours, I’d get anxious if I saw an ambulance heading toward his street while I was driving, I would ask for reassurance that he loved me constantly. Bear in mind, I have no reason to have these fears. My boyfriend is my best friend and has supported me through thick and thin and he’s amazing. One time a couple months ago I was being a bit snappy with him one night and I had the thought “only people who don’t like their partners are snappy with them” and it just stuck. Now I struggle with intrusive thoughts about my own feelings, do I love him, do I miss him enough, is my relationship going to end because this couple on social media broke up. I could deal with the thoughts about his feelings because he is so so good about making me feel loved but now I’m stuck in this constant guilt loop where I question my relationship for no reason then get anxious and feel guilty for even thinking that way because I think I’m manifesting it. Was wondering if anybody else in a healthy long term relationship has had this happen to them and how you talk yourself down :(

This is my first post and first time using this app. My partner knows I have ocd but we have been having arguments because I keep asking him super inappropriate questions about whether he loves me, is attracted to _____, is thinking of other people, doesnt feel attracted to me, etc. I get these obsessive thoughts and feel like I have to ask him to get rid of it or get reassurance from him that it isn’t true. But then I’m never satisfied with his answers, and keep asking questions until it comes to a point where the conversation is completely destructive and neither of us are happy. I see a lot of people talking about doubting their relationships and feelings for their s/o’s, but does anybody else have this experience? Advice? Is this relationship ocd too? I am 90% sure it is but the 10% is telling me I’m just crazy, obsessive, possessive, and jealous. I know insecurity must play a big part in why I obsess over these things, but I cant help myself from thinking these thoughts and asking him these questions. We love each other and he is doing his best to support me, but this is putting a big strain on our relationship. Lmk if you relate. Thank you for reading
