Confused,
First of all, welcome to Marriage Builders. Many broken and damaged and some very sick marriages have found healing here.
Without know what specific websites you are talking about, I am left to guessing about that, and maybe that's just as well. Assuming it's along the lines of what I think you refer to I would suggest that you ask your husband to look into
Every Man's Battle. They also have a section now for spouses, so you might want to check that out as well.
Now as for your marriage, Dr Harley has developed a plan for marriage reconciliation that has brought many couples back from the brink of divorce. Have you read the
Basic Concepts? The Marriage Builders program does work if both of you are willing to work the plan. You can have a marriage that makes both of you happy and one in which you don't just love him sacrificially but in which you feel in love again and get back that new love feeling you probably had when you first married.
So what would it take for you to let him back into your life fully? I know another promise to be good isn't the answer since promises seem so easily broken. Something like this can tend to divide a husband and wife. After all this is HIS problem, right?
But really, it is both of your problem, since when we are married, anything we do affects our spouse either for the better or worse, for good or bad, positively or negatively. I think you stand a good chance of having a long, healthy and happy marriage by working together to build a new, stronger, more fulling for both of you marriage and this is definitely the place for that.
I don't think you have to decide right now to let him come home or to divorce him. Right now that is really your only choices and I think there can be many other possible choices along the way, but first you have to examine what those might be. I would suggest that he look into EMB or a local counselor who works with men on such issues.
As for why it hurts you so much, I think a good part of that is because you feel betrayed since he has lied to you. One of Dr Harley's most basic concepts is that we must be honest with each other in all things. Finding out that we have been lied to can be devastating to our feelings for our spouse when we discover the lie. The way to repair the damage done by such lies requires complete honesty and a pattern of continued honesty before we can trust them again.
But part of that equation means that you must also be willing to hear about his struggles and failures since no man (or woman) can ever be perfect and we each have our own struggles to deal with. But facing the problem together gives you and him a better chance of overcoming what can only be called an addiction than turning away from each other or even worse, turning to someone else. That is a solution that seldom results in happiness for anyone.
Others with a more chat type of posting will be along soon, I'm sure, so hang in there and do a bit of reading, not just the basic concepts, but perhaps a few Q&A columns and maybe look at a few threads of other folks around here.
Again, welcome to Marriage Builders.
