I am an incredibly jealous bf and my gf knows this so she tells me she’s going out to eat with some girl friends of hers, and so I’m pretty sure she knows I’m a jealous type because I’ve told her in the past ,so I’m running an errand and I happen to see her and I see a guy getting into her car she sees me and says hi to me as if nothing is going on and so I act the same I act like if nothing is going on, and probably nothing is but I don’t know that, so I don’t know whether to leave it alone and forget all about it or bring it up? It’s just really hard because I want to show her I can give her space but I also wish she would have told me it was a guy with her.
