No, he’s made it “clear” that he’s “veered away from her and more towards me, promising me sexual exclusivity (whereas before he was fucking both of us and I knew it and was very angsty over it) and telling me that, while he’s not “dating” the other one anymore per se, they’re still close friends.”
*The posters in this thread *have made it clear that he’s a lying douchebag OR the OP is deluding herself (with some help from him, sure.) Either he hasn’t been clear and honest at all, or the OP isn’t being honest with herself, or she isn’t being honest with us. We’re all line-between readin’ here figurin’ out who’s not being honest, and most folks think it’s him.
I agree.
Oh, and as for the actual question in the title? I’ve met probably a quarter of my husband’s girlfriends, and it is awkward, even when one is in an honest and open open relationship.
