Why is this happening?

Just when I'm finally taking the steps to plan my escape route and get outta here, I get a slap in the face with the "I'm pregnant" line.

I was so pissed I told her I didn't believe her so she got all mad and took 5 pregnancy tests and showed me. Duddeee! I feel TRAPPED. I wanna get out but I couldn't take not being there for my kid. I never had a dad.
