It's still not the right time for us

OK so the guy I've had a crush on and a casual sex thing with since 2014 finally asked me out.

He has issues with alcohol and his hours have changed at work so he can no longer get to his support group. The poor guy actually opened up to me, I just want to help him but don't know how to do it apart from saying that he can come to mine at weekends instead of going to bars when he gets the craving. (I have a young child so I only drink when I'm going on a night out and I hardly ever have alcohol in the house)

I know we've said we will give it a try when he's in a better place mentally and I am so happy that he does like me back, I'm so upset that we aren't actually a couple yet.
