Sorry youre here with us a SI...but welcome...
If anyone could give me there educated guess I would appreciate it. I cannot forgive her but I would like to try and understand why she did what she did.
OK....ill give it an educated opinion...would like to add that I am NOT a shrink....one of my undergrad degrees is in psychology, so I know just enough about it to be a little dangerous...but I have researched affairs and why people have them - specifically women...(yeah...I had a wife cheat on me - and it blows).
Some women will cheat for the "high" they get from it....much like a junkie on crack.. they are addicted to the attention from other men. It makes them feel sexy, attractive, desirable, etc...and this can happen in otherwise "healthy marriages".... they just crave the attention of other men (mine fell into this category).
My wife was an alcoholic...clean for several years...but had an addictive/ compulsive personality...she traded one addiction for another....again, she got a "buzz" from spending money, online games, and yes...affairs. She was clinically depressed - and had the pills to prove it. She was abused as a child....sexually, emotionally....low self esteem, etc....she was "broken" per se...and had an unrealistic concept of what a "normal" relationship should look like...
I also believe that normal women make a decision to cheat, too.....some will think about it for a long time before they "cross that line"....unbroken women (in my opinion) will cheat if they perceive something missing in their marriage -lack of intimacy, no communication, they feel misunderstood, unloved, unappreciated, etc.....they feel their emotional needs aren't being met - real or imagined...
There are several kinds of affairs too... exit affairs, parallel lives, revenge, rekindled, etc.....each one with different dynamics, reasons and whys.....
I believe that most affairs are an escape from reality.....theyre NOT real, they are fantasy....rainbows, unicorns and fairy farts.....they are NOT bills, house payments, sick kids, trips to the grocery store....
I also believe that the best way to "end an affair" is to "expose it"...tell the OMs (other man) wife....give her proof of the affair....some on her will tell you she deserves to know, its the right thing to do, etc.....Bro, revenge works for me..... OM will probably toss your wife under the bus in an effort to save his own ass...and probably this isn't his first "rodeo".....
For whatever "reason" - your wife made a decision to do this....and its NOT your fault - yeah, you own part of any problems your marriage may have had "pre-affair".....you own NONE of her decision to cheat......
You have mentioned making the decision to divorce your wife.....that's ok Man, sometimes (actually I think "mostly") that is what happens when a wife cheats......its ok....once that trust is broken - its a real bitch to get back - IF it ever does....
Hope this helped......remember this is just my opinion.....
Keep us posted....
