I can't believe how quickly people can judge you and jump into conclusions! Just bec you are married doesn't mean you have to try to work it out and stick it out- what if you realize that you have made a mistake?
THEN YOU LEAVE HIM. You don't look for someone else first and then sample him and if he's better you leave and if he's no better you continue on in your marriage. Grow some bloody common sense and respect for the institution of marriage and monogamy. What the hell did your vows consist of, "I promise to forsake all others until Someone Else Might Like Me?"
You are ridiculous in your naivete. Tell your husband everything you've said in this tread and let him tell you if this man is interested / attracted in you if you think you're innocent of any wrong doing.
“The willingness to accept responsibility for one’s own life is the source from which self-respect springs.” ~Joan Didion
