Thomas,
Subconciously, you desire her to call you again.
Basically, she should understand her. If I am not wrong, she also knows she is playing a game. She needs the money from that man, but she knows you give her the option of a normal family. So...
She has been hoping to juggle two options at a time.
You mentioned she came from a poor family and she used credit card. For this sort of personality, material draws is huge but as she matures... you will gradually become more important to her... not because she loves you, but because she will be needing to settle down.
It's a general women psychological thing.
As for you...
You should and must close this case in this forum. It is usually best at this stage that you complete the divorce yourself and do not expose yourself to unprofessional noises.
The more you got yourself exposed to these morons, the more you will be confused, and likely end up in an extreme.
You have to take a break from this forum, cool down, do what you need to do, grow with this lesson, understand your wife and know how to manage this feeling.
It can be a time of depression... and yes, during this time, I DO NOT want you to be exposed to these noises. These people will make random guesses, sweeping statements and pretend to be helpful when they don't even care to think.
Don't ever reflect too much cos you will only, in chinese 钻牛角尖, thinking too much.
So your current most important thing is to find a life outside this forum because your wife can be expected to call you from time to time, and trust me... no matter what they say, you will be likely to 'spy' on that guy for her pictures.
There is NO quick solution to forgetting her and the marriage and bla bla bla since she took a significant role in your state of concious mind.
This is a pathetic crowd; if you were Kerin Peh and have friends like these people... I'd have suggested you leave them. They are NOT good company.
Whatever the reason for her infidelity... Just remember, you were the husband.
Now, please leave this forum for your own good. You are the only one who can close this case for yourself.
