Wife wants to separate at end of school year

[Bhuda1]

Its the last day of 2015. Needless to say its been a terrible year for me. I just hope things work out in 2016.

I have not been totally upfront about my situation. One thing I have purposely left out is my jealousy.

I have suspicions that my wife is having an EA with a neighbour. I have circumstantial evidence that there is more to my spouse's relationship with my neighbour than she is admitting. Part of my situation is due to me confronting her about her true feelings towards this neighbour, who I must add is married. I considered us good neighbours until I noticed signs of his infatuation towards my wife.

The unfortunate thing about the situation is his son is the same age as my oldest, and take part on the same sport teams. My evidence of this relationship as mentioned is circumstantial.

I noticed my neighbours over the top attention to my wife. Any chance he gets he texts her, goes out of his way to make sure he is always close to her when we have group functions. He makes an effort to always sit beside or across from my wife. When he sees her a makes a beeline to approach her.

When weekend we were away at a hockey tournament I watch my neighbour leave the hospitality room when he noticed my wife leave. I waited a few minutes and instead of taking the elevator to my room I decided to take the stairs. As I approached my room floor,I caught them holding hands and sneaking off into the stairwell. Obviously this surprised them because I caught them in the act. I said "NICE" and walked past them to our room. He took off and she followed me. We had an argument. My wife's explanation was that he was just trying coax her into joining the rest of the group and he was leading her back. In my eyes they were sneaking off to be alone. My wife then told me not to mention the handholding to his wife. I suggested that she was more interested in his wife's feelings than mine. I asked her then if she wanted to stay married and she replied yes.

Months later I noticed a text message on her cell phone which started with the words "Good Morning Sweetie" When I saw this I had enough. I asked her again straight out if there was more to her relationship than just friendship. She denied this and said they were just friends. I then asked her what his wife would think if she knew he was calling my wife sweetie. She told me that my neighbours wife would probably not like it. I can't remember what happened next. The topic has not been brought up since.

I have to admit that I have such a hate on for my neighbour now and I do not want to socialize with them anymore. Tonight they are hosting an informal New Years Eve party and I hate the idea of going. I do not know what to say to my wife when she will ask me if I want to go. Do I say I don't feel well enough to celebrate. Do I suck it up and go. I feel like I will be such a hypocrite if I go. I absolutely hate the idea of being near him. Its too hard to put up a happy front at this stage.

Any input from other DB'ers would be appreciated.
