I gotta stop being angry

So me and my ex/bd use to work at the same job he was there before me...when ppl started to find out we were dating all hell broke loose ! (Never shit where you eat) anyway it’s a few females who were jealous because they tried to get his attention at one point and he payed them no mind...so these woman would do any and everything to try to get us away from each other (we didn’t display PDA ) you would have never known we were even a couple word just got around eventually,also before I got there he would flirt with them so that has something to do with their actions..anyway this relationship became abusive and I’ve lost one child and have one on the way by him...we aren’t together and he no longer works there but I can’t help but to be angry at him whenever I see the woman who talked so badly about me , it hurts because he was abusive and for all of that they could have had him!!! I thought at the time this must be a really good guy he’s worth the trouble....man was I wrong so it angers me to be around them.... I needed to get that off my chest I just worked with those women last night and I was so hurt and angry I wanted to cry .... I’m home and better now lol
