My bf comes home on his lunch, and tells me he's done with life and just wants to kill himself.. half of its me and half of its his job.. I totally understand where he's coming from, and I feel so guilty making him feel this way because of my selfishness... Its time to make some changes in my life. He's the love of my life, and my son's father, I can't stand to see him hurting this way :'(
