Been struggling so bad financially right now while in college, been begging boyfriend/child's father to please let me have some money for gas, Wal-Mart trip & to buy some maternity clothes at Goodwill, he's promised me he will for a few days now & still hasn't. I feel like I'm doing everything by myself :( it breaks my heart that he doesn't care like he says he does
