You have so many problems you need to contact this friend everyday? That is overdoing it. I hope you are not talking about your marriage to him. That's emotionally cheating.

You admit to wanting to do sexual things if husband is on board. You have been flirty in the past. You are into this friend more than you will admit. Start cutting back on your contact with him. Go find a bff to share your story or better yet tell your husband your problems. He may be pushing you off to his friend because you have so many issues that its tiring to hear them.
