How do you know if he is really leaving his wife for you we have not had an affair?

It's important to communicate openly with him about his intentions and feelings. Look for consistency in his Words and actions; if he expresses a desire to be with you, but his actions don’t align with that, it may be a red flag. Additionally, consider how he discusses his current relationship—if he is genuinely unhappy and actively taking steps to address it, that could indicate sincerity. Trust your instincts, and remember that a healthy relationship is built on honesty and transparency.
