Would you kick him to the curb?

Leave his a$$, u shouldn't have gave him an ultimatum either. While u guys were separated obviously he was already looking at other things and other ppl....which means he didn't really give a crap about anything but himself. That should tell u ALOT about him right there. Let him go, ur young and can do 100% better. When someone locks thier phone there automatically creeping around on u and u know this. U can be with someone like that, it will drive u nuts and its totally unfair.. Please please let him go!
