My mom is my rock/best friend. You always have options. Just because society paints a certain picture of the "right family," I whole-heartedly believe the "right family" is the one that's right for your situation. I personally would never stay with someone I didn't truly love, because I wouldn't want to set that example for my child. (Just my opinion & not meant to offend, everyone has their own feelings about this!)
I'm feeling the same way hun! I just feel trapped and like I'm stuck. My boyfriend and I weren't together for long either and this pregnancy wasn't planned. I just feel like I don't love him anymore and after seeing how he is towards me and this pregnancy and how childish he is I just don't feel like he is the one for me. We live together now and we don't sleep in the same bed, we don't go out anywhere, we barely even talk. I'm ready to go my own way honestly.
You don't have to stick around for the baby. If your not happy then leave.
