I need to vent my baby daddy went out of town, he was supposed to be back today and well everything was good between us we were good or so I thought and then he never calls me or contacts me.. Come to find out he deletes me off his snapchat, and I had to find out from another person he's at some club drinking and idk what else. I'm so over it, I'm giving my daughter my last name. He doesn't deserve that privilege, all I ever wanted was the truth and I already dont trust him and he's doing nothing what so ever to gain my trust back. He is just a P.O.S
