Will he come back?

So I started seeing this guy, we slept together the first night and then continued chatting and sexting. Met up a couple more times without sex, just for walks and chats. Then he got distant and said he wants to call things off, doesn’t want me to message etc. things got a bit heated and he blocked me. After a while I changed my number and contacted him again, we chatted for a bit and back to the sexting then the same again, he says he doesn’t want to stay in contact and not to message him again.. so I haven’t, he hasn’t blocked me so what is going on? He came out of an 11 year marriage about 6 months before we started chatting and going through a divorce. Was he just rebounding with me and using me and is he likely to come crawling back or does he mean it when he says it’s over? I did get a bit hectic with the messaging the first time hence the blocking but this time I’ve left him to it..

Will he come back?
