What to do???

So I’ve been dealing with a guy for about a year now. I have a daughter who’s been anxiously wanting another sibling. Dealing with him I should’ve known something was up cause he would say he lived with his sister( whom I’ve met plenty of times!). So we would always chill at his sister house. Come to find out he has a WHOLE WOMAN at home!!!!!!!!! He doesn’t live with his sister he lives at another house with a woman who’s his girlfriend. Now… just recently I told him I was pregnant. All before he was telling me how he wants me to have his baby & get married. Now he is pressuring me to have an abortion because he says he’s already got enough on his plate. I don’t believe in abortion & this is something my daughter & I wanted. Any suggestions on what I can do? Please no negative comments cause like I said he lied about living with his sister! He is pressuring me everyday about this!
