How do you know he doesn't still think you are hot and beautiful?

Let's take a step back and look at the evidence. He married you. You're still together after 15 years. He says nice things about you. Sounds pretty good to me.

I know that when you've been with someone a long time, it's easy to doubt that they still feel the same way about you that they once did. I've been married about 127 years, give or take, and there have been plenty of times when I fear I've gotten too old or chunky or ornery or boring for my wife. She's had her own insecurities, too.

But I believe in taking people at their word until they give you a reason not to. When my wife says she still loves me and this (pointing to my once-rockin' bod), I believe her, and she should believe me when I tell her the same. It wouldn't be fair of either of us to suspect the other of being disingenuous -- not fair to them or to ourselves. We cheat ourselves out of joy when we choose to doubt what our partners say to us in earnest.
 
Yes, relationships change through the years. People lose interest and drift apart. It happens. But in other couples, something else happens: their love evolves and grows and matures. It's not the same as it once was, and that's a good thing, because it's better now. I love my wife today in ways I never knew possible when we said "I do" all those years ago. I'm willing to bet your husband feels the same way about you.

I don't know if he has given you reason to doubt his sincerity or not, but I do know that most guys aren't great at going through the motions. Most of them just shut down or stray or split. Your guy is still there every morning when you wake up, he's still jumping your bones (I assume), and he still tells you he loves you and thinks you're all that and a bag of chips.

Do yourself a favor: believe him.
