ooooooooooooo,ok, I see how you can begin to feel some kind of way. When a person holds on to a lie so hard and for so long, once you find out EVERYTHING they do will be suspect. But in the end, you have to handle this like a grown woman. None of us can tell you to end a marriage that we arent in. Its not our call..plus your giving bits and pieces (I dont blame you, I prob wouldnt have even bothered putting it on here tho, too personal).
Bottom line, you have to go with what you truly believe and not with what you think MAY be the case. I dont think you really want us to tell you what to do as far as keeping or letting your marriage go, but I think you needed an outlet to let out what your holding in and you may have felt desperate, depressed and angry and therefore you typed what you felt and to us it comes off a little nuts but too you it makes perfect sense because you know the whole story. The only one who can make the decision your seeking is the one who wrote the OP...
