My girlfriend is pregnant

I'm 22M. I've been with my girlfriend for 7 months and things have been good. I love her. We have been having sex, not as often as I'd like but we both have been busy. I am on the pill. I forgot to buy a new pack so I was told by the nurse to use a condom for a month. I didn't want to and told her that. She told me to buy the pill then. I did.<br><br>Well, I found out she's pregnant. I've been going to her ultrasound and I'm getting ready to be a daddy. I have no idea how this happened since the pill is supposed to stop this. I'm scared as I don't know if I am ready for this but I'm also happy.<br><br>The thing is, my girlfriend is a big, fat liar. I asked her when she found out she was pregnant. She said it was 3 weeks ago. I knew I didn't forget to take the pill that long. She said she did it on purpose. I asked her why and she said she wanted a baby.<br><br>I told her I cannot support both of you. I cannot afford a place for a baby. I cannot afford food. I work a full time job but it is only just enough to get by. I told her I want nothing to do with the baby. I told her I would pay child support. She told me she would be fine on her own.<br><br>I have never been in this type of situation before. I have no clue what to do. I am scared to lose her but I am more scared that I am going to be a father too soon.<br><br>What should I do?
