When I met my dh he was a new single father to three kids- 6yrs, 8, and 9. Our relationship quickly developed and within a year we were living together. I became mom, doing everything a mom would do. And I loved it, instant family. Before getting married we had decided to hold off having kids together to let the steps get used to all the changes. Then 6 years ago we had an opps. During my pregnancy the oldest started having behavior problems. Our daughter was still born and we decided to once again put off having a child, this time until the kids were out of the house. I'm younger than dh, he's 56 and I'm 37. So now the two oldest are in college and our youngest has decided to become a pothead. She's gone from almost straight A's to barely C's. She got caught shoplifting nail Polish from target and picked up twice for curfew violation. I desperately want a bio child. I want to experience sleepless nights, dirty diapers, the excitement of first steps, etc. But dh is wanting to hold off once again. I'm young, but I'm getting older. My childbearing days are numbered. Part of me wants to give dh and ultimatum, ttc now or I'm leaving. He says he wants to have a baby, but I'm not sure. It's not fair to me, and I'm starting to resent the kids. I don't know what to do.
