Most Helpful Girl
Yikes! What a loser! Anyway, the best way to forget about him is to get him out of your life... This means block him on everything you can block him on, including text message, if you have the right phone and software. Second, you need to tell this "friend" of yours that you don't want to see his baby... And if you already did, then you should probably evaluate your friendship with them, because they are only adding fuel to the fire.
You're doing right by telling him to leave you alone, but I think at this point, the best thing to do is ignore him from now on, even if you can't block his texts. Maybe he is just trying to get under your skin and see your reaction to all this. Either way, he's a moron.
