Flashbacks?? I used to be in bad relationship

Before I start I just wanted to let you know that my s.o has never laid his hands on me, Hit me or physically abuse me. He’s not about that life lol.

My s.o and I got into an fight... he asked me to leave and I didn’t want to bc I wanted to fix our problems. He got really annoyed so he tried to force me out of his room... he didn’t push me or anything. He tried to lift me off his bed but failed. I lost my balance and fell on the ground and I started crying lol it didn’t hurt at all (I used to be in an abusive relationship and I guess I just had some kind of flashback?? Idk what the fuck happened) my heart was pounding so fast I couldn’t breathe for a couple of minutes and I was bawling my eyes out. I couldn’t stop crying. He tried to apologize and to comfort me by hugging me but I couldn’t let him touch me. (I used to do this)

I had to go somewhere alone to calm down

He felt really bad about everything.

Does anyone else ever experience anything like this?
