When I met my wife she had a two year old daughter that she was bringing up on her own. There was no father in the picture at all. She had it hard but it was good that she would not give up the child. I thought alot of her for that.
We fell in love and married and I adopted my first child. She is 22 now and has a nice husband that I love. They have two children. They call me Pa Pa.
My sister inlaw had a few abortions and she has had bad feelings years later and has had miscarriages.
I would say you should keep it and your heart will thank you.
