My partner and I just found out we are pregnant. We have an up and down relationship. The arguments are always the smallest thing that will escalate. Every time we argue he says he is leaving me (even when he's the one in the wrong). Now I'm pregnant he tells me to do it alone and we can co-parent. My mental health is so low and I feel isolated because I'm not a naturally open person who will tell my family/friends. I had my first morning sickness and he didn't even check on me from the other room. I'm so sad and feel like I've made a huge mistake in choosing him as the father of my child, but embarrassingly don't have enough self-love to walk away.
