My girlfriend [24F] of two years told me [25M] she was on the pill but now I am a dad. What now?

I am 25 my girlfriend is 24. We have been together for 2 years and we were starting to talk about where we see this relationship going. She had mentioned she wanted to be married before having kids but we now need to reassess the situation. <br><br>We always had unprotected sex but she had shown me a pack of birth control pills that she said proved she was taking them. One day I noticed that the pack didnt change and I confronted her on it. She told me she had stopped taking the pill a year ago, it made her feel sick so she stopped taking them and I just never noticed she had a new pack. I felt like an idiot in having not realised she said she still took them but kept a pack everywhere. I just never really paid attention to it much, I was on the trust that she told me the truth. <br><br>She has been to the doctor and we are having a baby. She is 3 months pregnant. I am not happy this is basically blackmail. I do not want to be a dad now, I feel like I'm in my prime and this is going to ruin everything. I am not sure what to do. I am just taking it a week at a time. <br><br>I am considering breaking up with her. But can I do this with a child on the way? The thought of this just makes me feel sick. Is there anything I can do? I think I am just going to take it a week at a time and see where it goes. I just feel violated now.
