Yikes, maybe you should watch the show before posting...you got it all wrong.
1. It is not her husband's friend
2. She said she "tried" to spice up her own relationship many many times...
Shanni.....DON'T LEAVE YOUR HUSBAND. Wow, all I can say is, WOW! What an incredible man to still stand by your side after the horrible choices you have made out of your own frustration and misery. So very many people would truly appreciate that kind of loyalty...truly this is an incredible person you are with now and I hope you rekindle what you once had because this is a strong man of integrity. You can not see the forest for the trees. I hope you find your way back to your husband. If you take Greg out of the equation, would you still leave? If you are leaving "BECAUSE" of Greg, the relationship will fail. I promise you that. So will you be OK on your own when Greg is out of the picture - THIS is the question you really need to ask yourself. And for what it is worth...yikes...Greg sounds like a "FLAKE" and extremely immature. The fact he screwed around with YOU on his first wife, hmmmmm, would give me pause to be in a relationship with him as he will certainly eventually do the same to you.
Listen, you have it all and you are risking EVERYTHING on a liar and a cheater?
I hope for your children and for YOU, that you stay in your marriage. YOU can turn this whole thing around again. YOU can do it.
This whole "thing" you got going with Greg is "temporary". It will pass. Remain TRUE to your vows, count your blessings, and be thankful you have a husband that has proved to you he is loyal. For better or for worse? Good grief, could it be any worse for him and he is still sticking by you? All I got to say is I am impressed.
hmm...How long have you known Greg? They guy sounds like a pompous DORK.
I hope you make the right choice. You really don't look very strong as you are under the influence of Greg & your LIBIDO (which will mellow and then your stuck with Dork).
Stay with the one that will remain TRUE to you as your husband has already prooved.
Oh the drama. Kick Greg to the curb. It isn't over, don't let your "fantasy" DESTROY what you have NOW, which is real.
