This, of course, won't be popular but all you brothers of mine need to get out there and "blow out some cobwebs" if you know what I mean. You owe it to yourself. It doesn't have to mean anything serious. If the W is in it then sure, stick it out, be a good boy. If she's moving on then you owe it to yourself blow off some steam.
If you're over 40, or approaching it, you have to know that single women over 40 outnumber you at least 5-1. It's insane out there. With the digital age making this so much easier let me tell you if you're in shape (or if you need to, get in shape), your income is steady, and you're a good man then you will get absolutely swamped by wonderful women that would love to get to know you better. This advice is not for those working on R, obviously, but some of you guys need to know that you're still a catch. Trust me fellas, the waters are fine out there. Stop being so sad all the time. There will always be time to sit around the house and cry later. Your W's no longer get a say in your comings and goings so don't waste that.
