Is he into me or is just my imagination?

[TheBest!]

Now this threat is about one of my ex-boyfriends.
Sweet and rude, there for me and keep me waiting without a call to cancell.
We were together for 4 to 6 months. 6 years younger than me. We loved each other but I decided to break up since I was afraid of a relashionship with that age difference.
He is the kind of guy who thinks he is cute when he is rude and insulting but he does it in a way you don’t even notice.
He says he loves me but he confuses me. He invites to the movies or to play pool or once in a while to accompany him on his fraternity trips.
But when I tell him I love him and I can’t sleep with him being his friend. He says:”I don’t want to ask you to be my girlfriend since I haven’t changed, I am afraid to mess it up again and loose you…and he starts telling me neverending reasons (if it's my lifestyle(I have a lot of guy friends and hang out with them all the time) or his, that I am not ready for a relashionship, that he is too young..etc).
Sometimes he stood me up and whenever I called he said he had things to do and hung up.

Sometimes he sleeps over and he is sweet before you know what. After that he is the same budy, he doesn’t cuddle me or anything.

But then he get jealous when I go out with someone else even though he dated a sorority friend after we broke up.

Does he like me and he is afraid of a relashionship or he is not that into me
