Help me !

Boyfriends mom is upset I wanna keep my twins 😭 We actually work together and all she been doing is talking crap. She told my boyfriend if I don’t get the abortion then to not speak to her again. And sadly he’s a mommas boy and actually told me today I should go along with it. When we talked it over. I told him I want to keep them and be basically said if I don’t get the abortion he’s going to leave me. Remind you we already have 2 sweet girls together 😴 frustration is definitely the word idk what to do
