What does it mean when a guy says You're trying to make things difficult for me aren't you?

When this guy saw me wearing a sexy dress he said "You're trying to make things difficult for me aren't you?"

He is in a relationship and I have had sex with him before in the past. Also a couple of months ago when I asked him if I could practice Massaging him (I went to Massage Therapy school) he said he would love to but that he didn't think it was a good idea. And that he's trying to be a good boy and then he said see you around.
