Cheated on my boyfried, feeling so guilty

So I have a boyfriend and we have been together for about two years. . this weekend I gotta a phone call from a old friend he asked me to come hang out with him and go to a party so I went and I didnt tell my boyfriend because I knew he would freak out. So we were having fun drinking and everything and I guess I drank a little too much we made out and then after the party we drove up in the mts and had sex I dont know what to do I wouldnt have done it if I was sober I really wouldnt have he is just a friend and im in love with someone what do I do im going crazy I feel so gilty helppp meee!

you do need to tell your boyfreind about this
if he had done it to you im sure youd want him to tell you
be ohnest, try and tell him when hes not busy or doing anything important
re-assure him that you really do love him
and try and work things out from there

Jaz beat me to it.

But yeah, just tell him, he WILL flip out, but it would better than him finding out from a friend or something.

Plus thats a good test of love
