Pregnant @ 40

Okay, I guess you may say what is my problem…I am an older woman that shouldn’t care what people say, but here’s my story. I have a 3 year old by my ex-fiance. We were to get married, but he failed to tell me he was still married at the time and hadn’t gotten his divorce prior to our wedding day and the ex-wife showed up at the wedding!. Total disaster and my family has hated him every since! We broke up in 2002 but kept messing around with each other. I got pregnant Again in 2003 and hastily had an abortion because I was worried about what my family would say! (They didn’t know that I was secretly seeing this man that made a fool of me at the altar) But even after ALL that, my ex-fiance and I tried to make things work and got back together in 2004 just to break up 3 months later. Well, lo and behold, this past month (February) we were intimate and I got pregnant again. I am around 7 weeks!! I truly don’t want to have an abortion again because I felt so depressed and guilty about the last one. My ex wants me to keep the baby (he wanted me to keep the last one too, but I didn’t listen and I am more worried about what my mother would say. I know, I know…..I am 40 and still scared of what my mother may say. I guess I am just wondering how I should I break it to her? My little girl would love a little brother or sister and I came from a big family and I can’t imagine her being the only child. I am thrilled and scared at the same time.
