Pleas don’t chew me out but am I the toxic one?

Okay y’all please don’t say hurtful things, I’m really going through a lot right now and have no friends since I just moved here last year. My boyfriend and I have been together for a couple years and I’ve never been the jealous type ever! He has many friends and can do whatever he wants I’m not controlling in any way. However we had an incident a few months ago where he cheated on me with a hooker. We’ve been going to counseling to try and work things out since I’m now pregnant. I hate confrontation and I come from a very toxic home and don’t ever want to be that way. Is the way I’m speaking to him toxic? Also, we do talk in person this is a one time thing where I had to text it. We will be talking in person later on. I don’t want it to seem like I’m attacking him but I really am hurting from all of this. The Facebook thing was an add. We were watching a video and then the next video popped up as he was exiting and it was a girl getting dressed and he hurried to try to click back onto FB to see it. Right in front of me. It never bothered me before and is only bothering me now that I know it’s not just innocent looking. That he actually acted on it. I just want to make sure I’m not being to mean.
