AIO GF went out with a male "friend" who has been very open about wanting to date her while I was out of town for work

She did her makeup nice, and went out for dinner with him, just the two of them. Then they went back to his place to watch movies and stayed there until around 4 in the morning. Honestly, I don’t even know how late because it’s the next day and she still hasn’t messaged me.

She said she is allowed to have male friends and I agree, but not hang out like that with people who have openly said they want to date her. She says she respected me by telling me, but I don’t see how that’s respect. I say she doesn’t respect me for even considering it, much less doing it
