I want to have children some day but my girlfriend doesn't. We've been together 6 years and I'm 34 years old and not getting any younger. She's happy not having children and says she wants to focus on her career and never really wanted to have the burden of a child. I'm contemplating leaving her and ending this since I know I can be with someone who wants children. I love her so much, but I want something more. I want to be a dad and I want a family.
