The man I like A LOT is moving....What now?

To go for a long distance relationship or just to remain friends? I'm a 29yr old single mom. who has not been in a relationship since her 2007 divorce. I meet this guy 9 months ago at a bar. Because he is so much younger than I am I brushed it off as to he's too drunk. I amused him and gave him my # figuring he'll forget he's even got it. The next morning he called. And he's been around since. He's the tall dark and handsome type. Im extremely attracted to him. It took me a while to get feelings for him. I was looking at his age and situation a lot. He confessed feelings for me mid summer but I told him that we couldn't do anything about it. We remained friends. Late fall I realized I have feelings for him. I told him. I would like to make it work. To give it 1 year and see where we stand then. He said he would like the same but to wait to see if the pending holidays weren't making me feel lonely. Holidays came and went. And we are now in what I can only describe as limbo. He's always talked about going back to the south. I told him I can't leave the state and not sure I could do a long distance thing. Well now I really like him and I know the feeling is mutual but he's leaving mid February. I told him that as long as he was committed I would comit as well. We have no label right now. And he's hinted of keeping it like that. I'm confused. The only thing I know is that I like him a lot. So does my son and he's really good with him. Do I attempt to push for a long distance relationship? Or do I take the mature adult rational route and chalk it up to a nice fling?
