Had an affair and now I'm confused, need advice

Hi everyone, so here is my story, I'll try to keep it as simple and brief as I can. I've been having an awesome relationship for past two years. everything was great and we have made the best of it. I love my girlfriend and she loves me. however, recently I met this girl at school and she's amazing. We became friends, I did not know she was interested in women and she didn't know I was gay either. We began to meet more and more often and even though I started to develop feelings for her I did not make any moves. After a while the question came out and she asked me about my orientation, I told her that I was a lesbian and I told her I was in a relationship, she admitted she was into women as well. We were thrilled to know. It was obvious we were attracted to each other but nobody said anything until one night we discussed the fact. We also discussed that I was in a relationship and we both decided not to do anything and that it was better to remain friends, but of course something happened, well a lot happened, we became lovers. but I became too attached to her and I think she did too. I was feeling so guilty that it was consuming me. My girlfriend started to notice I was acting weird so I decide to stop it. I didn't tell my lover what was wrong I just disappeared.She has try to contact me but I haven't been answering phone or emails. I feel horrible because I miss her like hell. I want to call her, be with her, I'm honestly sad that its over. Of course my sadness is affecting my relationship and I don't want to hurt my girlfriend in any way. but I cant help to feel this way, that's where I am right now. any advice will be appreciated.

 

I don't know that the right thing is as clear as Duck suggests. I'm habitually honest and a serial confesser so telling your girl seems like where I'd start

There's this whole other school of thought that confessing only serves to ease the conscience of the guilty and further hurt the victim (@ Dr Drew circa 1998 LoveLine teenage education)

Either way you *need* to decide which of them you want to be with

 

^well then I agree

tell your lady what you've done

and if you love her and want only her, tell her that too

You never know how she's going to react, but don't plant the seeds of deception and leave them there to grow

 

Thanks for the replies, After thinking about it I decided not to confess what i've done and spare her the pain.
