The guy friend agreed to me about moving on, and just on a casual note once asked me out for a lunch, I agreed and didn't tell my boyfriend because I didn't wanted any fights with him, I was aware what's the limit I have with my friend, so I just went for an hour.
Few days back my boyfriend checked on my whatsApp, he was literally reading all of my chat with him, he got to know that I went out with him, I clearified him everything that see only this this happened, it's was a casual meetup.
He was literally dragging the same topic for days, I felt like is he doubting on my character or what? When I clearly said him that nothing is there with that guy, I got too frustrated once that he is constantly judging me, I slapped him, and he slapped me back!
I am too much guilty about slapping him, but how should I deal with him doubting me when I did nothing wrong?
