1) This isn't about me. I run a tight ship. I wouldn't give a guy the boyfriend label if there was any chance that he has a wondering eye. Before being official, all those numbers on his phone must be deleted (unless they are child hood friends), every thot unfollowed.
2) The troubling aspect of this is that, this relationship is still new (less than 1.5months old) - he should be all about you, especially since you've already gave up the goods. He shouldn't be already scouting for other women like he's still single.
3) This dude did the same thing to his old chick, liking IG pics of random women and as you can guess, he blind sighted and curved her ass shortly thereafter.
