Relationship

I am 21 years old and I have 2 daughters both out of wedlock. The first person was a narcissist who managed to get me to close the door on God fully. Since I started 8th grade I kept trying to fit in with everyone else even if it meant turning my back on God. I’m currently engaged to the father of my second born. She’s almost 4 months. We have been married legally in VA. We have an appointment with my priest tomorrow to start the process to get married in the church. My husband isn’t Catholic. He is a very godly person and plans on being confirmed in the church. We have been having problems and I know I’m the problem. Tonight he asked me what do I care about. I responded with “you doubt everything I say, so it doesn’t matter what my response is.” He said that’s all he needed to know and went to go sleep in a different room tonight. I’m tired, my head feels cloudy, and nothing feels like reality. I find myself getting overly angry at the smallest things and snapping. I don’t want to lose him. I believe he is the person that God sent back into my life. I don’t know what to do.
