Boy problems

I have known this guy for the majority of my life. We hooked up once and we’ve always send each other nudes and sext each other as well. He’s been in a relationship for about 1 year already and he continued to message me wanting nudes, wanting to meet up, and sext me. I would try to short talk him and tell him that he had a gf that he needs to respect her but clearly he doesn’t care. A couple of months ago I found out he’s going to be a dad and me still messages and doesn’t care. He’s always asking me what I’m doing. Does he even love his girl ? What does he want from ? His gf not pleasuring him, idk I just find it weird how he has always messaged me during his relationships.
