Seeking advice not necessarily in an ENM context, but since many couples practicing ENM are better communicators than most I figured this would be a good place to start.

I and my husband are almost 40, been together since 20, married 15, and been ENM for about a year.

My husband, since the day I said yes to going out with him, feels like he doesn't deserve me . Honestly I think he's wrong and tell him so often. He's more laid back generally while I'm more type A driven active type.

Sometimes he gets these low moments of depression where he's more self depreciating than usual. Just recently I got my masters degree, and while he's thrilled for me, he also has been seeming... not actually depressed, but he said "one day... I feel like you're gonna figure out you can do better and run off with someone you deserve."

Like I said. I constantly tell him and show him that he's enough. He even says there's nothing specific I can do to "fix him".

Have any of you experienced this with your partners even before the ENM? I know it's mostly trauma from his youth and is well above my skillset beyond loving him as much as I have and more but... any advice is appreciated. Thank you.
