What should I do, I’m scared to tell my mom.

Key

So I’m pregnant and just turned 18 years old on the 16th. My baby father is turning 21 in a couple of days. My mom already thinks he is too old for me. However, we BOTH want to get an abortion and he’s paying for it and everything. I know my mom would be hurt that I didn’t tell her that I got the abortion but I feel like she would be more reasoning with me. But she would be very hurt that I didn’t tell her. However, I don’t want to tell her before because I know for a fact she is going to want me to keep it. And she’s going to be my at my baby father’s head. My baby father is somebody I talked to and was about to be in a relationship, but he broke up with me. He is still in my life though, he said he going to help me through all this and still be friends but he doesn’t think a relationship would be best for us right now. So it’s not that he treats me bad she just thinks he is too old and she has never met him before. What should I do because I don’t want to act off of my emotional state I am in.
