What to do?

Hi guys,

There's this guy I was seeing before but we broke up because he wasn't mature at all and I couldn't deal with it. Now he comes back saying that he wants us to be long term friends and that he wants to know how I'm doing and that I am keeping well.

Since he started uni, he's changed alot, he started going clubs quite often, partying and drinking and taking women to hotels. He says he wants to meet up and have a meal together.

I don't know if its normal for guys to be like that in uni and maybe it is, I really am not sure. But from his behaviour, I don't feel good meeting him or contacting him anymore, let alone wanting to be long term friends as he says. I don't even get why to be long term friends for, he's got lots of friends he goes out with, so I couldn't be bothered.
