I’m Separated (F42) and in a situationship with a (M29) not sure where this is going and need advice.

I’m currently separated with two kids. I’ve been over my husband for years now and we’re starting divorce proceedings within the next month. I’ve been seeing this guy that I’ve known a long time but recently shifted from a friendship to a sexual relationship. We see each other on average once a week but it’s mostly just us getting together at his place, maybe cooking, getting take out, hanging out then having sex. We get along amazing the sex is very good. I feel like I may be in love with him and he certainly behaves in a loving way towards me.
The question is I find myself torn between wanting more and keeping things as they are since it fits into my current lifestyle. Actual dating sounds daunting anytime soon but I also don’t know if I’m being used here or even if I’m the user. We have a really intimate relationship we talk about serious things like our past, our goals and dreams etc. for example he says he doesn’t want kids (that would be a deal breaker for me I don’t want anymore). Despite this real connection we have, the future for us seems really vague. I know an honest conversation is in order since this has been going on for 6+ months but I have no idea what I even want or how to approach this without freaking him out because I am 90% happy with this arrangement, I’d probably only want for more dates outside! What should I do? Leave things alone and wait until I’m officially divorced to talk about this?
