There's a guy I really like, but he really likes someone else.
In short, he took the plunge and asked her out and she recently rejected him. He was pretty upset about it and came to me for comfort, talking about how much he likes the woman and how upset he is that she's not interested.
A few days later he has asked me out.
It's upset me even though I've liked him for a while. It's clear how much he likes the the other woman. I feel like I want to say no?
