GAG, JMO but I say go for it! XH is a man that you may be interested in dating. Yes, you have history with him. That may give you an edge in knowing how to read some things. That said, it's like you're starting over with him. Didn't you say that you were the initiator when you first started dating? You know the drill, and besides the worst he could say is no. If that happens, don't take it personally and just keep your expectations low.
You're handling this wonderfully! XH seems to definitely be responding. Good Luck!
