Most Helpful Guy
Whether or not he dumped you or not, you were the most important part in his life at one point. So I'm sure he wants to know how you are doing. I do that the same to my exes, although I am still friends with them so it's not really checking up but more of just going through my video story feed.
Guys have an ego, we can be dating someone new but still wanna know if our ex has found someone better or worst and such. It's fine, let him see. Have fun and snap great things. Let him know he lost a great person. You are winning (;0THIS IS NOT RELEVANT ANYMORE
