DH and I got married on the understanding neither of us wanted children...eight years in he changed his mind...he was 30 and had a 'now or never' moment.
We agreed on 1...we had 3 in three years...do I regret it??
I don't know...I am not a natural mother imo...but do try very hard at the mother role and so far my DC's seem to be thriving...they are all pre/teens now.
Do I wish I had my old independent life back...I dunno...again things could not have worked out the way I imagine...maybe I wouldn't still be married...maybe my career would have imploded...maybe it would've all been the opposite.
I chose to give my DH the children he wanted...I was under no illusions as to how much hard work they would be or how my independence would be altered, it was a choice made with a lot of reality involved.
It has been harder but better than I imagined...this is my life now and I am as content as I ever expected to be....so I suppose I've got the life that has made me happy...even if it wasn't the one I had planned on.
