Dear Miss Emily,

I've been dating this girl for a while, and I met her at a party I had a bit back. We are really close, and I love being with her. It's just at this party she hooked up with my friend, and I just can't seem to get it off my mind. She says she regrets doing that 110%, and I believe her. Her past doesn't matter to me because of what we have now. I just want the thought of her and him hooking up outta my mind. How do i do that?    

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

Well, it seems to me that her past does matter to you.  That said, it might be unrealistic to expect you to change your attitude about this, but I'll try.  This girl hooked up with your friend before you two got involved.  I know some guys have a double-standard concerning their behavior and a girl's behavior, but that wouldn't hold up in court, so to speak.  Jealousy is a wasted emotion. In this case, what came before you entered the picture is really none of your business.  She might have had second thoughts about what she did but, again, that's only information she expressed to you, and hopefully not in the form of an apology.  We all have regrets.  She's probably pretty cool, and has a lot to offer if you approach this in a mature manner.  And that means, life happened to her before you arrived on the scene, and it will happen after you leave it.  Lighten-up, grow-up, and admit that, in the real world,  there are things that are not in your control, and you just simply accept that fact. Don't ruin a good relationship unless you find her out on the street corner turning tricks.
