Should I go ahead with my pregnancy?

I just found out I'm pregnant. I'm 25 been with my partner for 6 years and we have been engaged since Feb.

I have already had an abortion when I was 20 and I will never go through that again it was one of the worst experiences of my life.

We are both close with our family.

His concern is that we don't yet live together, or have a house together and thinks it's going to be really hard once there is a baby because of all the expenses and thinks we are not ready.

We both work full time jobs and I also have an online clothing business.

I'm really stuck and don't no what to.

Has anyone had a similar situation?
