I'm sure I will get scorned by some people but..here it goes. Okay so, just to backtrack, I've been dating my boyfriend for about 7 mos and we live together. After I moved in with him, I saw that he had major insecurity issues. He pretty much was always thinking I had bad intentions or was seeing somebody else. And of course I have never even thought of that because I love him very much. So, I finally got him to let go of that recently.
I'm not sure if it was b/c of his insecurity or my own but I've never distrusted him. NEVER. I've always felt like he was a genuine guy. Up until recently....I've just had a funny feeling about him for the past couple of weeks. Everything has been great between us but I couldn't help but think about this feeling that I have that I had started to not trust him. So, yes..sad to say..I went and made a fake myspace profile (we both have profiles of our own.) and just put some girls picture on there and was going to send him a friend request just to see if he would respond...yes I know. I should have NEVER done that. I regret it very much now. I've never stooped to that level before and i feel dirty for doing it. BUT I did it nonetheless...well, he denyed the request so I felt good about it. and just never really thought about it anymore. Well, last week sometime, I checked that profile and he had sent a message just asking do I know you. That's it. It pissed me off that he would even ask it..but like I said I was the one in the wrong for even making the stupid thing. It was dumb.. I shouldn't have done it. So I asked him about sending her the message and he pretty much just said that he thought she looked familiar and that he was kind of being a smartass by asking do I know you because as he says "she can clearly see I have a g/f". SOooo once again, I was going to just leave it alone b/c it made me feel like such an idiot for even thinking anything. Yesterday, I went on the profile to delete it and low and behold I had a new message..but this time, HE made a fake profile just to talk to this "girl" and this is what he wrote:
"whats up? Take a guess at who the mister E man is.
HINT: we have already talked a little but in a not so safe environment.
I don't know why but I feel like I need to know more about you."

I'm completely heartbroken by it and I don't know what to do. I've thought about it all night and all morning. Of course I don't want to tell him that it was me but then again I want to confront him about it. I just feel like an idiot for even doing this...but I did it and now this has happened and I don't know what to do. Please tell me what you would do...should I just delete the profile and pretend this never happened? Should I respond to his message? Should I confront him about it and end up looking like an idiot???? Should I just leave him? What should I do???
