Hi Miss Emily-
I'm turning to you because I don't know what else to do.  My boyfriend and I have been in a serious relationship for about 7 months now.  Even though I just turned 21, our relationship is far more in depth than most people our age because he has been living with me for nearly the past 4 months.  He was in a hard place where he was, and so he moved in with me and my family took him in, and love him to death.  Everything has been going really, really well for us for the quick advancement in our relationship.  My only concern is this:  When I'm not at home (I take classes and work part time) he talks to other girls he's met online.  It wouldn't bother me if I knew there was nothing going on, but I have walked in on him talking to them, and he gets rid of it quickly and tries to act as if nothing was going on.  I know it probably wasn't the smartest move on my part, but I have logged in and read his conversations, and although it hasn't been anything too awfully inappropriate, I am still upset and hurt by the things he says to these girls. (he tells them he's single, and lives alone, and flirts with them a little).  I have confronted him about the situation, and he tells me that it's nothing and that they're friends of his from back home (which I know he is lying).  He's told me that he would let me know if there's something going wrong in our relationship, and nothing has changed emotionally or physically between us since this has started.  I'm just so confused on why he's doing this? Do you have any thoughts on his reasoning? And what should I do?  I'd hate to let him go.
If anyone else has any advice- please email me.. chelsey_lynn32@hotmail.com... please!

-----------------Miss Emily's advice--------------

One thing I've noticed in the letters I receive from women (and girls), that I don't often get from the guys is this:  Women either make excuses, or are too kind when it comes to explaining bad behavior in their men.  You seem to think he's a great guy in many ways, yet he lives with your parents (who have graciously taken him in during his run of bad luck) and, while you are at work or at school, he's conversing with the ladies on the Internet as a show of total disregard for you.  Friends of his from the past, or not, it shows a side of him that proves he's not ready for the kind of serious relationship you think you have with him. This guy is getting his jollies, at your expense, and he lacks a sensitivity chip to say the least. You can tell him to stop what he's doing, but he'd probably find a way to do it without you knowing.  It would be one thing if he had some female friends from back home and was chatting about you and the weather, but what he is saying to these women is not appropriate for a guy who is in a committed relationship.  Watch your back, because this is a sign of trouble ahead with a guy who appears untrustworthy.
