<human>: Can you condense the text into a few key points?

My long term BF (4 years) and I recently broke up, he cheated. That, however, does not cancel the fact that I miss his companionship terribly. We still technically live together, but rarely spend a night under the same roof with him sleeping over at his friends/family when I sleep at our house and vice versa. We are figuring out the living situation though.

After I broke up with my BF I was going through a lot of pain. I ended up getting drunk and sleeping with a guy I ve known for almost a year (we weren't friends, however). he had just gone through a break up himself and is in the same place I am emotionally. We have been seeing each other for a couple weeks now, almost every day. The sex is amazing, and so is his company. I realize that I start developing feelings for the guy. I know it is due to the recent break up and me being vulnerable. I just can't help it. 

I understand that this is unhealthy, but just can't help thinking about him.  I know he is into me and it is not purely sex. but I don't think he wants anything more than a casual thing. should I distance myself from him? should I still see him but take it slow?
<bot>: Emotional mess after a break up; have feelings for a guy I just started seeing. I don't know if I should distance myself.
