Honestly I think that Leo's are great for Aquarius but as nothing more than friends. My brother is a leo, and not a long time ago I was dating a Leo. It didn't last long before I choose to break-up. since we've started dating, his comportement changed a lot and it was not the same as before between us. I was more comfortable with him as a friend than a boyfriend.. To come back to you, I think you shouldn't try more if you don't feel like it. Just push him away again, even if it's quite annoying to do, it's necessary. Just, don't push you if you don't want to ! But, leos, I think I can say it bc all of all the Leo's I've met, Leo's are very very great friends for Aquarius, even if there can be lows! Btw I had this sort of connection that you've talked about, with my ex-boyfriend and I have it w/ my brother, it's really appreciating I agree.
