I've been with my boyfriend for a year and a half. We've been living together since March. During the first month I moved in I found out he was getting dirty texts and picture messages from other girls. He swore he would stop and he did for a while. The girls would continue to text him but he wouldn't respond. Finally it got to a point where it became very annoying so in June he just decided to change his cell phone number to stop them from bothering him because he saw how much it was upsetting me. I just found out that not only did he change his number but he got a second line and a second phone to let these girls continue to talk to him. He ended up hiding this phone in his car. He says he never met with any of them and I know at least for a few of them that was true because they live half way across the country. However some live decently close. I love him and I know this is something that we can work on under the condition that he cuts the crap and gets rid of the other phone and all the phone numbers. ( which he said he will do and we will go together to get rid of the number) I've asked him why he does it and he says he doesn't know. He doesn't know why he needs to have them around. He has said he loves me, wants to marry me, have kids. That I am the love of his life and that I am the only family that he has since he doesn't talk to his. He's also said that when he gets off the phone with those girls he appreciates having me around even more.
I'm not looking for advice and for anyone to tell me to get away as fast as possible or anything else. I know him and I know that he really is a good person (that may be hard for some of you to understand but I know him and he really is). He treats me like gold aside from the situation with these girls. I don't know how to explain this but I know him and I know he isn't doing it intentionally. He had a really bad childhood (child abuse etc), he no longer talks to any of his family (he's 27) and I am pretty much the only stable relationship he has with anyone. He's told me I am the only family he has. He stops talking to those girls for a while and he really tries but something always lures him back. The only way to see if the problem is fixable is to find the root of the problem and I am trying to figure out what that is.
Does anyone have any idea WHY he could need them in his life? Why does he always run back to them? Is it an insecurity ( which it probably obviously is) but would there be something more in depth?
Any help would be really helpful and I thank all of you that read this and respond for your time.
