Just a vent ..

I’ve been dating a guy for almost two years he has a child with this lady and I accepted him like that and trusted him well almost two years later I come to find out she still loves him and wished they had fought for their family I cried a lot to the point where I felt so bad I felt like I was going to faint because I don’t want another woman loving the man I do and this woman has a child with my man so I know the love he has for me is nothing compared to the one he has for her I also found out they were going to have another child but she aborted I felt upset because to me it’s like they had two childs and they did that cruel thing to one .. I also found out he told me that when were mad or arguing he would run to her idk all of this is killing my head he’s acting like everything is okay like he never did anything wrong my problem isn’t that they still have love for each other because I can’t change that but that he dragged me into this just to use me
