my girlfriend is pregnant and i don't love her as much anymore because of her attitude..i want to be with her...I lost my job and having a hard time finding one...i moved because i wanted to be able to take care of my baby..ive done all i can to get back but no one has hired me....i know i need to be there but what good is it gonna do if i cant buy a jug of milk..she's 22 weeks preg...i need help on handling the hormones...before i make a decision to just leave her alone...i went down one weekend to see her and she told me that i could see her she didn't believe i was there..so i left and it made me mad..i didn't call her or txt her for 2 days...ive been emailing her telling her good Morning every single day.... but i stopped that also when she said i couldn't see her what can i do..
