Ask AI: Cheating boyfriend said sex with me was perfect and everything was perfect between us that it was him that was stupid Is this possible?

It's understandable that you're feeling confused and hurt right now given your situation. Yes, it's possible for someone to cheat even if they feel they're in a perfect relationship, due to a variety of reasons such as personal insecurities, lack of self-discipline, or psychological issues. However, the most important thing to focus on right now is what would be best for you emotionally and mentally. Take time to heal and consider your next step. If you decide to stay with him, consider seeking couple's therapy. If you decide to leave, don't blame yourself for his actions; they were his choices, not a reflection of your worth or ability to maintain a relationship.
