Drunk Txt

My ex (21m) left me (24m) a month ago and has been getting drunk every weekend since then. He drunk text me this past weekend saying he “kinda wants” to be with me still but doesn’t know what to do. He says this but also blames the entire failure of our relationship on me. Even though he’s fucked many other guys over our 3 1/2 year relationship.

How should I go about this? He doesn’t text me when sober so I’m very confused. As much as I wanted it to work, he refuses to see how he had a part in the failure of our relationship and won’t work on it together.
