help...what should i do?

[l8tr g8tr]

You may get many good, interesting & diverse answers. I hope you do, kinda like a menu of choices. Hopefully mostly good suggestions.

You know very well that what you're feeling is what happens to so many marrieds. The urge, the wondering about what else could have been possible Is it still possible?

If you're trying to stay away from involvement w/ another partner [on the sly], then perhaps some fantasizing in acceptable ways might be useful.

No, I do not mean social media....that's way dangerous, way too many unknowns.

Novels & movies [DVDs] where the protagonist [That's you!] is involved in romantic crises that move you. Get'em from the library, free.

Share the best novels/movies w/ your closest GF's. As long as you keep fantasy world separated from soccer-mom world, you're all right. Its harmless, but fun!
