5 months ago.. My boyfriend all of February it was texting different girls an had sex with one girl that had sex with all his friends she's obviously very easy. I found out 1 month later an tried to end it but for some reason he begged for another chance and I just saw something in him I haven't seen in anyone else 1 month later I found him texting 1 other girl but I was pregnant and had to get an abortion because I have the number 1 negative blood type in the world an the doctor said the baby would come out with disformations and health issues because I didn't get a shot before I got pregnant (I had no clue I had to or I would of) anyway after the abortion I was very hurt an cried for days and he was there for me like I've never seen him before we were great again an till this day he hasn't been messing around he said "something just clicked one night if I kept doing stupid stuff is lose you forever" and he was right, and he really is being the best he can be an doing every last thing for me for every 4 months now.. My issues is getting over the cheating.. Not the texting other girls but having (sex 1 time with another girl) I talked to her first she said it was only one time and gave me all these details I did not need to know.. But I don't want to hold it against him because I took him back and that's wrong of me to do. But I just need tips on how to get over it, he's really working on gaining my trust back and I'd NEVER take him back again if something ever liked this happen again. our families talked we talked and everything just seems perfect and in its place right now an I'm loving how things are going I just get so upset when I think about that situation.. Hell also go "if I could take back one mistake in my life I've ever done id take that one back" and is always going on an reminding me how things will never be like that again and I have trust for him this time it won't, I really see it in his actions these past 4 months I can start to let my guard down little by little I just need tips if anyone's ever been through something like this!!
