advice needed

I was doing ok with rocd, sometimes the thoughts pop up in my mind but i was able to control them and not letting them control me. Last week i was with my boyfriend, i was doing fine but then something happened that irritated me and i tought "omg i can't live with him if tings are gonna be like this". When i noticed what i was thinking, i instantly panic and i started to think that maybe i don't want a future with him and thats why i was thinking that. The thing is, a couple of days before that, i was telling him how much i would like to have a cat when we both live together in the future. My parents and even him told me that there's nothing wrong with what i thought, and that sometimes, when we are angry or irritated, we think negative things that we don't really mean, and i'm trying to see it that way because i'm really struggling, but i don't know what to do
