Search Results: look last all day

I’ve noticed some odd behavior from my wife over the past few months. One day last week, a guy came to the door asking for my wife. She shooed me away, and about a minute or two later, he just simply left. A few weeks before that, I arrived home from work early and saw a guy leaving our house and getting into his car and leaving. I asked my wife both times and she said not to worry about it and it’s nothing. Other odd behavior I’ve noticed is that she doesn’t want me seeing her texts or Facebook messenger messages. She’ll get a Facebook message but won’t let me see and when I try to look later on her phone, the message is gone like she erased it. Now, she barely talks to me and won’t tell me if she’s mad at me or why. She just says she has to take care of some things around the house. I haven’t suspected my wife of cheating in the past but this is sounding like cheating. What do you all think?
