Abortion?

I have wanted a baby for so so long and me and previous boyfriend who had been together for 6 years while trying to conceive, and after 1 miscarriage for 2 years later nothing happened and our relationship eventually ended because of other reasons. Now It seems that as soon as I was starting to to myself maybe it's a good thing you didn't have a baby yet, finish school, go out some more. I am pregnant and I am not as excited as I was before because I do not love this man. I feel very selfish for both wanting to keep the baby and wanting to get an abortion so I could have babies later on with someone who I could give the baby a really good life with.
