>My husband has commented on a lot of pictures, asked women how long they are in our city for, and has mentioned that he is traveling to a different city and wants to meet up.

Oh yeah.

He's actively trying to cheat on you.

Id screen shot all the evidence (after confirming it's definitely his account).

And wrap it up in a pretty box with a pretty bow and gift him divorce papers along with the comment longs.

Then tell everyone in your life and his life exactly why you're divorcing him. And then move on with someone else.

You're 30. This is the last age to really blow up your relationship and still be able to fairly easily recover and find a new partner and marry and have kids before it's too late.

However if you stay, you'll end up in your late 30s and 40s 20 years out from retirement with kids by a man who likely never changed making it much harder to leave and land on your feet.

I'd consider this the universe giving you a gift.
