Search Results: talking to an old crush

My ex and I broke up a while ago because of his drug habits, and it's been hard to move on. Since then, I've been going out and meeting new people, leading to new crushes.

Guy #1: we've met up twice, the first time being an introduction by a mutual friend. He was sweet off the bat, and I was horrifyingly nervous around him. Second time we hung out was at a festival; he had my number and called, saying he wanted to hang out. He basically called/texted me until I got there, asking me "where are you? Are you here yet?" And other similar things. When we met up he seemed more animated and comfortable, often hovering around me and trying to involve me with his friends. The friend who introduced us says he may be taken.

Guy #2: we went to school together for 5yrs. He's a great guy, and I have liked him in previous years. Only recently. We started talking and hanging out. I invited him to my bonfire tomorrow and he said he'd come, asked if I ever tried Molly, and said he'd bring me some to try--for just me and him before the party, meaning he wants to hang out. I flirted more openly with him and said he was cute and suddenly he started talking more and using emojis a lot.

Guy #3: he's a drummer for a local band who invited me to one of his shows and to a party via facebook. When he first saw me arrive he came straight up to me and introduced himself and said he was glad that I could make it. after the show he invited me to another show and said he drive me there and back. Later he randomly asked how old I was;that's when I told him about my birthday party tomorrow he said he would come.

Then of course is my ex. We've been through a lot together together for two years, and even now we are still some of the closest of friends. He says it's not my fault we broke up, but his, and that I made him as happy as I possibly could have. Just recently, we actually had sex, and we acted as if we were still a couple.

So what do I do?

So this guy that I have a crush on has an 8 year old sister battling with leukemia. I'm thinking about talking to him about maybe starting an organization/fundraising group to help make awareness n hopefully to support her and others battling with it... is this is a good idea or is it too much? I don't want to push him away by talking about it.
