I’m emotionally wreck right now!

So I recently found out I’m pregnant I wasn’t trying to be I told the guy to wear a condom . I was drunk so I know it’s my fault but I thought he was wearing one..few days later he admit he came in me and that I should go on abort the baby. I feel like this is not fair I was trying to prevent not getting pregnant until he hit me with that! I’m against abortion that’s why I tried to prevent this whole thing from happening.... I’m thinking about getting an abortion but I feel like what he did was wrong! Hopefully I’m not overreacting...
