About 40 years after my 1st wife and I divorced, I married for the second time just a couple years ago. Her name is Michelle, she'd never been married, and she's quite a bit younger than me; she'll be 40 on her next birthday. I knew she had me heart and soul within just a few months after we started spending a lot of time together, so I asked her what she thought about moving in with me.
Basically, she told me to eff-off and asked me what I thought about getting married instead. My argument about our age difference didn't hold up to her "If I'm old enough to live with you, I'm old enough to marry you." Plus, she pointed out (unnecessarily) that chances are pretty great she'll outlive me, and so what about our home and stuff? I know my kids would leave her be, but would she still have some sort of legal battle, like maybe with the state or whatever?
So, marriage totally simplifies all that, and also, I'm not up to dating. And Meesh is kind of a home-body, too. Well, she works and takes classes at a local college, but that offers the luxury of not constantly being in each other's way. We have common interests and we both see the funny side of life, so we have a lot of laughs. My kids and grandkids adore her, I like all her family very much.
So, yeah. It's working out really well. After 40 years of bachelorhood, I did not expect this at all.
