Marriage HELP! Think I might be infatuated with a younger man?

It is definitely normal to be attracted to other men. We are only human. It is up to you though not to ACT on it. You are married and should know your boundaries. The fact that you say your husband is "boring" means there is something missing in your marriage. It seems like you are living vicariously through this guy. Either fix the rut that you are in and talk to your husband about what you want or get out of the marriage. Don't cheat because it is not fair to your husband or your child. Plus this kid is 24 do you really think he wants to settle down and be a parent to a kid that is not his? I am glad he turned you down and has some kind of sense. You should too.
