I just found out I'm pregnant and we've been seeing one another for 2 months

Yeah... I feel so dumb. I had my birth control appointment and was ovulating when I took the plan b and I just got a bfp. We are both not even divorced yall even though we are definitely not with our exes... ugh. I've been separated from my abusive ex for about a year. We do really like one another but have been taking things slow. I got a faint line the other day and we talked about things. He was super supportive and sweet. I'm just wondering how this will work? I feel torn. I have 2 girls, ages 10 and 2. He has a 15 year old son and a 8 year old daughter. My parents are extremely.... controlling but loving but they don't even know I'm seeing him and they haven't allowed me to "date" since leaving my ex even though I'm 32. I grew up very very Christian and termination is extremely frowned on. But, Im so scared.... so scared. I would like to keep the baby but not keeping it keeps swirling in my mind. It took me 3 years to get pregnantwith my 2 year old so I'm shocked. Is this some gift? Should I keep the baby or consider termination? What would you do? Please be kind, I can't talk this through with anyone...
