I'm so hurt

Denise
Hi everyone I'm new to this site. I just need to vent to someone other than people I know. So my bf and I been together for almost 3yrs in November. I got pregnant in the end of December 2013, but lost it in January of 2014,Than got pregnant in feb 2015 and lost it in April of 2015:( I've always had trouble getting pregnant, but I have 3 kids. 18,26,14 yrs old. This guy I love so much!! Like since the first day I got with him. I'm still so attractive to him. So October 27th he told me he wanted to go to the gym. It was 11:00pm. I was upset because it was late and I was tired. I work and he don't. I finally said, go if that's what's going to make you feel better. Fast forward to 4am I wake up and he's in bed with me. I go back to bed, wake up at 6am we make love. Mind you, he ain't to into doggie style, but we did it in that position. So I go to work come home @4pm than I have school at 5:45 I get ready and his phone rings, and it says Arron!!! I said answer it? He says no I'll call him back. I go off to class. I get a text from my ex sister in law. Saying I have something to tell you it's about your man! I give her a call and she tells me her bf saw my car and my bf with some nasty girl, who sleeps with every tom dick and harry. And that there is rumors that she has an std. so I call him, and asked what girl have you been having in my car? He says only your daughter, I said don't lie ! Who is kat?? If you been messing with her you need to let me know! She has hiv. He admits to it. I go home and sock him up!!! Cut his clothes and snatch the phone I pay for out his hand and find her text. Come to find out he was seeing her for 3weeks! Taking her to the movies, with my money, in my cars, buying her pads, gel, etc . With my money!! So I asked him did u sleep with her??? He admitted that he did that one time:( which was October 27. I told him we are going to get tested. On oct 28 we go to the clinic! We get a shot for gonorrhea a pill for chlamydia! We go do labs two days later. We get our results back and positive for gonorrhea and chlamydia!!! But everything else negative! I'm still with him , and want to give it another shot. But I can't trust him. I don't need him financially , because I own my own home, I own my own cars, I work hard . I support my kids. But I love him. And I want one more baby before I get to old. I don't want to have to bring another man around my kids. But I don't want to be alone. Idk
