My wife asked me what would I do if she cheated. I asked her if she did cheat, and she became evasive and said, "Well, oral sex isn't cheating." Another time she asked the same question. Again, I asked her if she did cheat and she said she wouldn't tell me until she knew what I would do. She also insinuates she is having or has had oral sex with other people. Is she cheating? Should I worry?Please help.
