split up with you + wants you back = he's having life issues right now but due to his condition, probably can't be in a relationship. if you asked, he'd probably say yes, but it won't take long for another break up because he's going through ****. once the second break up happens, then you begin a spiral.
happened with my mom and dad, don't do it. drop him, talk to him in 6-12 months. IN PERSON, never on a text if you want to reconnect.
