Really looking for advice.

So I am 20 years old. My ex boyfriend of a year and a half and I got a place together back in March. We then broke up beginning on June. We continuesly would still hook up with each other but it was just a hook up for him and meant everything to me.  Well clearly it's now caught up to us. He wants me to have an abortion and we've only briefly talked about it. I went over to the place he's been staying(him and I still rent together) to tell its confirmed I'm pregnant. I don't want to have an abortion but he does. We didn't really talk much and I had to go run errands and i asked if it was okay if I came back later that evening to talk. He said yes. Welp it's the next day and he won't reply back to me opens my snaps nothing. May I mind you he is 26. I don't know what to do with the situation at all. Someone please give advice.
