😔😔just need to get this out

So my bf has cheated on me before, but I'm trying to trust him again. He really seems like he's straightened out and he proposed to me and I said yes (which might have been a mistake), but we were engaged and I found out I was pregnant after. He's been asking if we'd try for months so I thought he was excited and wanted our baby, he acted like it too. He was so sweet about it. But this morning I got jealous about him adding a girl on fb because he's used fb to talk to girls before and me getting mad made him mad and he said some really hurtful things like maybe I should break up with him and just get an abortion. It broke my heart...💧💧💧💧
