I’ve been seeing this guy who is getting over his ex. I’ve been supportive, comforting and there for him but he won’t ask me out. We both know that we’ve fallen for each other and are deeply in love, so I don’t see the problem. How do I get out of the friend zone?

First off stop using the term “Friend Zone,” because either you are a friend or you are someone with the ulterior motive of another kind of relationship.
Next pull up your big girl panties and talk to him. Ask him out. Put it explicitly. All he can do is say no.
This is going to sound a bit harsh but If he wanted to ask you out he would have.
If hes still hung up on his ex then hes still hung up on his ex. You cant rush the healing/grieving process just because youre sweet to him. Your support and comfort cant cancel out his lingering feelings for his ex.
