I just wanted to say I understand your situation completely and am myself struggling with the decision of whether or not to leave my husband. Just wanted you to know you not alone here it's a very big choice with possible consequences but if you're not happy in the marriage you should really look hard at the pros and cons of staying or going without thinking about the g/f. I don't think theres really any advice that anyone can give you to make it easier just follow your heart and what you feel. I wish you luck and hope everything works out for you. It's tough but I just keep telling myself it's going to work out in the end, but I do think your wife deserves you to be honest with her about it. I plan on telling my husband just because even though I've been dishonest and unfaithful to him I don't want to carry this forever knowing I was a liar. Good luck to ya ~Pixelyzed
