Were you definitely exclusive or not? I still, in general, agree with this PP: “ Generally speaking, even 3-4 months is still early enough that it's still casual dating and neither parties owe each other anything.“

3-4 months is nothing. I personally think too many people define commitment way too soon into dating....and it ends up being bad marriages because they committed way too Warri when they still should have been exploring other options rather than prematurely being exclusive. Relationships can be really long. Less than 5-6 months—that is nothing.

Look man, if she did this once, there is very good chance she will do it again. The other dude isn't the only one who was sleeping with, I can guarantee that.

His timeline would put them still sleeping together when we were 3-4 months into dating. She admitted it was more hens once but didn’t want to say anything because she realized she really liked me. I broke up with her and I’m moving on.

Sorry Op. It sucks now, but you are much better off finding this all out now than say after an engagement or marriage. You'll find someone.
