I called him a week ago. We talked for an hour on the phone mostly about him. I asked if he wanted to go out and grab a bite to eat and he said he was busy but would call me another time and get together. He hasn't called back Should I call him again or leave it be. I did not mention anything just caught up on his life and a little of mine.
I do know he is single and has not been with anyone in at least a year. I don't know if he is bi, st8 or gay

I don't think this guy is interested in you at this time. He turned down your date offer and hasn't called. You know he hasn't had a partner in one year and you're not sure of his sexual orientation. I'm not sure either but all I know is if he likes you (as a friend or more) he'll reappear. But don't hold your breath. Get out there and meet new people.

It wasn't a date offer just a catch up over lunch offer but I know the reason y he said no and I know it wasn't a lie
