Should i have his baby or not?

I am in a huge dilemma. I am so confuse, angry,hurt, and ashamed, I am 6 months pregnant and I am disgusted with the father!!!!!!For one, I cant believe I ever found him attractive and I cant remember if it was even a physical attraction to begin with. I think I was bored last yr. when we started talking and needed my ego stroked again by a male and that was him.I convinced myself that he was long term relationship type which he was and which was what i was looking for at that time. He never cheated and he genuinely loves me but he is soooooo ugly its not describable, His teeth are huge, filled with gaps, and yellow as hell not to mention the stench. He is just so not a looker at all. I only ended up pregnant by him because i was convinced i couldnt conceive becausi i had unprotected so many times and never got pregnant so when i found out i was shoked and now im angry at god. Out of all the men i slept with and wanted to get pregnant by, why did he let him impregnate me??? I told him i wanted tohave his child and part of me did part of me didnt and part of me was just talking. He is jobless. unambitious, uneducated, and just pathetic!Y wud I want to have his child i feel like im diry just knowing something from himis in me!I apologize for this being long but i needed to get this out sooo bad!I have more things to say but i wud be typin all night. ALL ADVICE WELCOMED!!! Good advice plz, dnt make me feel worse im only 18 and sorry for typos but im tired.
