AITA

Am I the asshole to assume that while I’m at work she’s bringing over her boyfriend to do the deed?My wife who has been cheating on me for about a month now. I politely said, if you are doing anything please out of respect don’t do it at my house. I pay for the house, rent and utilities. And she know she hangs out with him on her off days at my house while I’m at work. Just kind of in shock that I’m the asshole, when she’s openly cheating on me without remorse or guilt.
