This will sound bad but hear me out?

My ex broke up with me about a month ago and she is going through a rough time. THe thing is her birthday is coming but i still want to acknlowledge it and get her something because i still want to be her friend. Now.. the thought came to me about what would happen if she was so moved that she wanted to "have fun" for old times sake. I loathe the 'friends with benefits' concept. The man side of me says hell yea... but the real part of me does not want to go down that road unless she wanted to get back together with me which i dont think would happen. If i refuse, would she be insulted? Its a thought in my head. Advice?
