I wonder if it really is a 'dream' though? Maybe its more just an assumption of what your life would look like....
You are the same age as me and I know we grew up surrounded by a societal norm that says women should aspire to marry and have children. Its so all pervading it oozes out of every single advert, tv show, movie, magazine, book etc, etc.
It is very VERY hard to develop your own personal rational vision of life that matches the realities of who you really are, when the whole world is screaming that you will only really be appreciated/successful/attractive/useful if you get married and have kids.
Realising your life is different to the life you expected to have is painful and difficult - but it is a chance to work out if the life you always thought you would have is actually the best life imaginable for you personally - or if, just maybe, the life you ended up might not even be a little better in the end....
I personally swallowed the societal BS hook, line and sinker, and had a child when any idiot looking at me, my personality, my strengths and weaknesses, my partner and his strengths and weaknesses would probably have said 'hell no, that's a terrible idea'.
I had planned to have 4 kids...the only thing I can say in my own favour is that at least I worked out after having 1 that I had been sorely mistaken in my life goals!
Even now it still hurts that I don't have the kids I always imagined I would....even when it is so very obvious having more children would be a disaster for me, DH and indeed DD.
So I guess I'm suggesting you do what I apparently couldn't and can't. Re-assess your dreams objectively. Realise that having kids as a dream is almost certainly societies dream for you...and not your own. Find your own dream and chase that!
