My gf of 1 year just confessed to cheating on me 2 months ago...

Her not telling you isn't too protect your feelings, its to protect the guy she fucked. Not telling you is just her putting him first - again. If he was a real friend he'd tell you, and anyone other than a friend or family would be easier to handle rather than harder anyway.

Excuse the typos, phoneposting.

A lot of guys here are speaking from experience getting cheated on. I'll give you advice from the other side.

Ten years ago I was a 20 year old spit fuck that cheated on my gf. And let me tell you, at that age, if I did it and got away with it, I would do it again. I fucked this girl the night before my gf b'day and I didn't have a lot of shame for it.

I broke it off from my gf. She was upset , but I knew I was gonna cheat on her again and I didn't want to keep it up. I never told her I cheated on her and I think that was a good call....I think it may be worse to tell the person you betrayed them, easier just to seperate. Either way, if I were you I would definitely get out of there.
