Okay so, weird night. Girlfriend of 4 years comes to mine in tears saying that, the other night, her ex-boyfriend kissed her... and she reciprocated. Now they were about 16 when they split up, and we've been together 4 and a half years after that, so I never really thought them hanging out was an issue, I trusted her implicitly. He's always held a candle for her, and he's always made attempts to flirt with her. Over the 4 years we've been together, it's come down to me threatening him to stay away from her a few times.
Thing is, I never trusted him, but I always trusted her not to do anything. I never even dreamed she would. I mean, it's just a kiss right? That's what I told her. Everybody slips up, and if I fucked up like that I'd want her to forgive me. But thing is I never have, and I'm still pissed/upset obviously. She says she regrets it, and she's never going to see him again. I appreciate she told me, if I found out via other means I might have been way more annoyed.
I know going to GAF for relationship advice is pissing in the wind a little, but I plan to stay with her, and I don't really want to tell my friends/family about this because it might impact our future.
