Your past is haunting you, causing you to be insecure and as a result your think your husband is cheating on you. If you continue this behavior, it's going to destroy your marriage and you will continue to behave in a destructive, dysfunctional way. In other words..."stop it!".
I agree with vmvnpv, you really should speak with a counselor, priest or professional to sort out what has been done to you in the past and how to move forward. Night clubs and clubbing is not good for a marriage. It's just asking for trouble, so find better ways to go out with your husband and friends, where you can have a good time and not fear that he is looking at other women, or women looking at him. Good luck.
Have you ever talked to someone professionally about this? A lot of your past is playing into your current relationship and the only thing it will accomplish is you pushing your spouse away. Talk to him about what you're feeling. Men and women look but as long as they don't touch it should be fine. He married you for a reason. You make him happy. He thinks you're beautiful. He loves YOU. No one else. That's why I think it may be a good idea to get some therapy. A professional will be able to help you sort through your feelings before something happens to your marriage. Good luck!
