The nerve of some men

This dude whom I met online that I used to talk to on a regular basis is really feeling himself. Him and I used to be cool but we had a falling out and stopped talking. Somehow we started talking about but this time very infrequently. Every time he always hits me up on some he wants to marry me and fly me to where he's at tip. I'll stop talking to him for a few days and he ALWAYS hits me up first.  Now he's acting as if I'm sweating him and people are just going to eat that up. Blah!
