Is my man...cheating...?

My man isnt usually the type to go out. Recently his new coworker asked him to go downtown, so he went. When my man came back home he said it was "so lit" and that his coworker is cheating on his wife. Tonight he said hes gonna go with the coworker..same bar downtown. He also asked me to cut his hair..its 10pm.. I also asked if I could go hangout too but he said he doesn't want me there because its just him and his coworker. He mentioned taking me to meet him but he changed his mind on it and doesn't want me to meet him anymore.

Am i overthinking? Why do i feel like his coworker is being an influence? Idk..
