He's living in my head rent free

It's very annoying. He's been asking me out for ages, we went out once and it was much fun. However my lifestyle is and has been crazy for the last 2 years. As much as I wanna go and enjoy, I can't just as yet. I'm in the middle of a messy seperation and going to court etc. Plus health issues on top of this, so I have other priorities before considering dating.

I feel bad for shutting him down and I've not really explained whats going on. I don't even know if he'd care to know to be honest. The last time I said I couldn't go cos it wasn't a good time and he thought I said I wasn't well. He sent get well wishes and since then not even a message to ask how I am, So you'd think the fact he hasn't checked in on me would deter me from thinking of him. Nope I still think of him. No matter how busy I am.
