My Boyfriend Is Acting Different Ever Since I Lost Weight?

I've lost over a total of 70 lbs and 20 in the last few months. I have been receiving way more male attention and it hurts his chest so badly, he keeps saying when I get fit to not leave him. When we were in the gym a black guy very handsome was checking me out greatly, deep eye contact and all. He later complained about how he felt invisible when he has done it to me plenty of times, right now 3 attractive black men said hello and were smiling from ear to ear, he also complained and says I'm too cocky... What is all of this about?
