At this point I could just laugh at myself

Pls help Am i overreacting/ thinking . Me and my bf was outside taking our dog out and then my bf was ready to go inside . The leash got caught under our dog and I told my bf two times to take it from under there . My bf told me “he (our dog) will be alright “twice . You know how when you’re taking your dog outside to useit on the leash and sometimes it gets under the dog between its leg and private area. I was thinking about that and my kind automatically goes to what if since my bf ignored my twice and told me our dog will be alright that means he sexually abused our dog bc he didn’t take the leash under there right away and said he will be alright . I thought my bf was pulling on the leash and the leash was probably rubbing against our dog under there . My bf said he didn’t pull it tighter but he was trying to get our dog to go back up the steps where my bf was and I guess my bf was trying to get my dog to correct himself since my bf was walking up the steps and our dog didn’t and tried to go another way. Just a brief summary about me , I have pocd and another theme where I constantly wonder if my my bf is a secret bad person and I also wonder if I am too . Lately I’ve been paranoid about what if my bf SA our dog even tho deep down ik he’s not like that but my mind will take innocent things and make it into soembtig. Not only does it do it my bf but I also question what if I’m abusive too . Pls help . I was trying to get over it but I’m like what if I get over it and it was actually somebtign bad that happened and I just disregard bc I think it’s ocd 😞 this is awful . So now I have to come here for reassurance bc I can’t tell if things are a real concern or not . I feel like for a long time I’ve lost my touch of self judgement and touch of reality . But what if I’m being gaslighted idk . Lmao so ridiculous!!!!!!!!! I’m sure some of you have seen more posts of mine . I would love to not post anonymously but I can’t risk some evil person exposing my statues to my family and friends . As I’ve typed all this I’ve calmed down but idk anymore I’d rather just say whatever . So tired of worrying about stuff .and then it’s like what if I didn’t explain this correctly and ppl don’t understand what I explained … oh well lol. And then my bf is mad at me bc he’s tired of me accusing him or assuming horrible stuff that’s he’s not intentionally doing. Now that I’ve calmed down I feel like this situation is not what my mind is making it seem but the what ifs and what if I just don’t know what a real concern is anymore bc of my constant ocd torturing me everyday
