Ten years of marriage: A "Dirty Trick"

I lurk on a few on-line forums that discuss mixed orientation marriages, closed loop relationships and challenges that straight spouses face.  Below is a story from one of those forums.

This quote isn't exact;  I cleaned it up to make it easier to read.

Seven years ago, and three months after the birth of my third child, my husband told me he cheated on me with a man. Four years before that he had done the same thing, "but not all the way."  Both times, after much crying and begging on his part, I took him back.  After the second time we talked about his attraction to men and how it had been there for years.  We also saw a marriage counselor.  Within two years our sex life dwindled to nothing. By then he had quit therapy, and no matter what I did, our relationship just got worse.

Last Spring my hours at work got cut so I was making a lot less money.   Pretty soon we fell behind on our bills. In the Fall, when he realized how bad our finances were, he said he wanted a divorce. What a slap in the face! After all I had forgiven NOW he was done?!?

His mother was sure he was cheating on me. I asked him if that was true, over and over again, but he kept telling me, no, and I was over-reacting.  He still lives at home but he spends almost no time there, unless he has to watch the kids because I'm working.  Well, last Friday I found a Valentine's Day card from his "lover" along with gay porn and a bunch of condoms. I feel like the last 10 years was a dirty trick. I immediately called him on it but first I made copies of the love letter.

One thing that makes me so mad is that I have defended him to both of our families.  He says that I'm the problem because I'm bad with money.   The reality is that, if I had known what a liar and a cheat he was, we wouldn't have been married last summer anyway.  After I showed him the Valentine's card he finally admitted that he was having an affair and that it started more than 11 months ago.  He also told me that he has gone on vacation with this man and he has had sex with him in our home with our children asleep. I am so angry, I can't sleep. I am sad for my kids because they think we have a great family. The poor things don't even know about the divorce yet.  After all that he has done to me I don't even want to look at him.

This woman feels like her 10 years of marriage was nothing more than a dirty trick.  When you read her side of the story, it sure seems like he continually lied to her and strung her along.  Then, once he found a boyfriend, he decided he wanted a divorce.

Stories like this are pretty common but every time I read one I am astounded by the selfishness and cruelty described.  When you 'love' someone, this is how you treat them?

On the other hand, something else that constantly amazes me is how often women will choose to overlook the obvious.  The guy cheated twice, admitted to a life-long attraction to men, and doesn't have sex with his wife.  What was she expecting??

I suppose I'm being cruel for thinking this, but...wasn't she's fooled twice and now it's shame on her?

****UPDATE****
 For those who are interested, here are a few more details about this woman's situation:

I went with a don't ask, don't tell policy. I had come to terms with no sex and having a gay husband. It wasn't what I wanted but I was working with it.  Slowly, over the last 3 years, he has gotten more and more disconnected. I see now when he started fooling around. I have a gay friend at work who said he had seen him on the gay website adam4adam and knew it was my husband because our kids' pictures are posted there...that was over 2 years ago. My co-worker would not talk about what he saw but said about 1 year ago he stopped posting.  Now I've found out that's when the boyfriend started. So go figure.

I don't know how to react to this.  Now I have many more questions than answers.
