Abortion or not?!

So I found out today I am pregnant. A little bit about my situation: I am 23 years old have an excellent full time job and am pursuing my masters degree part time. I still live with my parents but am saving for my own place in the near future. I have been with my boyfriend for almost two years. He is 35 and extremely successful. Has well over a six figure income, his own place in the city, nice car, etc. Technically Money would not be a problem for us. However, we are not engaged and not sure if we even are goig to head towards that direction. It is very important for the both of us to be married before havin children. Even though we both are doing well in our lives, we are not ready for a child an have not reached our full potential career wise. I don't know if his is the man I'm going to marry, and I am not ready for a child. Are we just being too selfish ? Idk what to do
