What the hell do i do in this situation with my man?

I rarelyyy go out. Maybe like 2 times a year, as a mom i dont go out. But i did the other night. I had a lot of fun! Singing and having a good time and being myself. And i was excited and happy texting him and then he said “oh so youre shaking your ass with another guy there? 🤔” and i said “no baby. i love you and I would never disrespect you like that.” And he went “mhmm 🤔. Lol jk. I guess” and i just changed the subject. But like. Wtf? I cant have a good time and hes not trusting me? I think theres no point in a relationship without trust. Ive done nothing to make him distrust me. 2 years together and ive never gone behind his back or cheated. I dont know how to address this and help him to trust me. Most would day just leave, but like i want to make it work. Ive addressed it before and im tired of being questioned when im not doing anything wrong. Should i address it in person next time i see him? Like i was in a good mood rn and texting him and thats rare for me, and then he got lowkey upset for something that i didnt even do? And brushed it off and said hes kidding. But ik hes not. And no i wasnt drunk
