Maybe I know what to do 6

I walked up the stairs without her hearing me the other day. I came around the corner and she hurriedly closed out of FB messenger. I could be something. It could be nothing. But an alpha doesn’t worry about these things right?

I wouldn't worry, but I would note it. Your W has BD'd you, has a male friend at work, and isn't engaged in any intimacy with you. Then you catch her closing out of FB Messenger quickly when you come into the room. RED FLAGS

This doesn't change anything you should be doing, but it does seem to suggest the strong likelihood of an EA. Be vigilant and observant. But also just keep up DBing...hard.

I would resist the urge to snoop. Those of us that have done it have later regretted it. Some things you can't unsee.
