I'm in the same boat from a man's perspective. I'm now 37, haven't come across Mrs. Right, and I want children, too. Of course, I have to be careful checking out the background to make sure any woman I date isn't a pill head, alcoholic, or kook. Not that I'm judging, but I can't mix Serbian/Irish with any of the above. Bad temper I can deal with; druggies have to fix themselves. Besides, it doesn't look like she's around the corner, and that sucks. I can't think of anyone else that would love to be monogamous, a good dad, and a great husband. Unfortunately, life sometimes seems to just happen no matter how much you plan..."man plans and God laughs".
Adopt? No chance. I want to know the background of the child I'm adopting and the medical and mental issues that run in their "family".
