My girlfriend and i want different things.

Those sound like some extreme clashes...and you either compromise or don't, but with such extreme differences compromise may not be possible...I don't know but we seem to only have one shot at life really and a person should probably at least try to leave their legacy and be happy....but then again reading that...your marrige house and beach thing and holidays could be supported by a woman with a career...heh...if you ever worry that you'll end up alone then something might not be getting fulfilled int he relationship, because trust and committment are a huge part of love...but then again I'm no brain shrinker person or expert either..blah blah

It's either you two communicate well about that subject of having kids and come to a decision to have children or if not, you might have to do and go with your own decisions even they will be hard decisions, but the good for you.

I think everyone has their own choices... as you two have made one... its always difficult to decide what is right and/or wrong in any relationship... it depends upon the common objective... i always believed in having a common objective. Having a common objective is as necessary as having a baby... a life that both live for... not only as a person but also as a soul... either one of you will have to change.. it depends on how important this relation is for you guys... and who's way is the correct way to go about it...

If she doesn't want kids and you do, it's VERY selfish to force her to have a baby just because you want one. I'm like her -- no kids EVER. No man will ever change my mind or force me to have a baby just so he can play daddy. It's my uterus, not his. If he wants a baby, he can leave. And I suggest you do the same. She's not going to change her mind and if you change it for her, she's going to resent you and resent the baby. There are millions of other women who want children. Trying to find someone who doesn't is the hard part.
