well 31 weeks pregnant, yay but the father of the child can just careless and we live together. we had a bad argument today. back story (he cheated on me with the b!*@# next door) and I have to see her everyday! the other day me n him was out and he said "what's up" to her in front of me. I feel as if it was disrespectful, for the fact yall talk behind my back! so that's where I'm at in life currently. I have no where to go ( for now) currently looking for my own place but damn. I've been with this man for 4 years. ive been with him since I was 17 and he was my age I am now (21yr). like if u were so unhappy why didn't u leave before u got me pregnant. we both wanted this. he wanted this, but why fuck it up now!?. sad he still ain't home and it's 12am. I don't need him but I feel so alone.
