I'm pregnant and having mixed feelings with my complicated s

My fear of being pregnant has become a reality..

I found out from my doctor that I was officaly pregnant. It was so extremly shocking that I haven't even thought about what to do. What to think. Like I've been sitting in the same spot for the last two weeks and haven't moved and nothing has changed.
My situation is complicated. I've been dating a married man for quite sometime. It was never a serious relationship. It was more of a convienance. But I won't lie and say I didn't have feelings for him. Just not love feelings. In Nov. I was in a car accident and because of it I was taken off my birth control. It was the nuva ring. Not being able to continue the birth control in the timely period it is required to be put back in I had to wait another month. In late Nov. we had our meet-up and not thinking of anything because I assumed everything would of been fine considering that I already had my period for that month didn't use protection.
I finally found out in Jan. that I am expecting. As much as it is a reality check for me and him aswell.. I found myself at a crossroad. Should I consider an abortion? Or become a mother. I'm currently not in the greatest financial spot I'd like to be in. I'm still living at home with my mother. And would I be able to offer this child the samethings if I waited till I was ready. I've told my partner about everything and he supports any decision I make. Now its up to me to make one. I'm not sure it would sit well with me if I choose to get an abortion. Considering I've already had a misscarage.
Also I feel that going to that extreme would it be the right outcome I'm looking for? Or just running away from 'responsiblity'. I'm not seeing how this will effect everyone elses life. Like him, his wife, and I. What him and his wife do I don't care for. I never expected a relationship out of him. But I find it hard not to if I was to keep the child. It is a little thing that has been on my mind and I could use some guidance or advice to my situation.

hey hope...This is a very hard situation and my heart truly goes out to you. There is nothing easy about any choice you have to make.
Do you have any children now? You mentioned you had a miscarriage before. I don't know what that was like for you but for me it is very hard.
And there is a difference...between a miscarriage and choosing it for yourself. But I understand you circumstances are leaving your mind in a storm.
Here are the things you need to consider
both are forever...abortion or keeping this baby
both have "consequence"
I think it is very easy for a man to say "I'll support you whatever you choose" If you you said "I want to keep this baby" How would he really feel? Would it matter? If he says "no way" would you do it on your own? Do you have friends of family that would love you all the way through? This is so important.
Do you want children. I mean, at all. now or later. Do you desire that?
Have you talked to anyone about this...aside from here. A friend?
I hope you truly do have support. If you decide to keep the baby, I hope you do have people that are around you that will encourage you, help you get connected with the right resources that may be of help to you.
I just want you to feel like you have a choice in the first place. (of course legally you do) but I mean in your own heart...your own life.
There is help out there if you need it. I know.
I'm here.
