I think your MPA was one of those people that didn't want to be with you. It wasn't you it was her. These people, whether employee, tenant or spouse man/woman are people that want to quit and move on but don't KNOW how to do it. Or are afraid to say goodbye, it's over, I want to move one. They like to be kicked out , thrown out or even by court order. IT is some weird DNA they have in their heads. I can't explain it, low self-esteem, co-dependent and I can't figure it out. Some times - I have seen this - people will cheat to be dumped so they can move on. Hidden bisexual tendencies? I can't find it but I have learn to detect this kind of behaviour I have seen it so many times in different forms.Marry? I wasn't even able to date one. And she wasn't even an SP. She was an MPA.
Moral of the story. Even if you are the type of guy that can handle being in a relationship with an SP, chances are she is not capable of handling it herself.
I agree with above statement ,people don't have an outlet, if they are introvert I think they crack. Their EGO gets in the way big time. Also leave work issue at work is a good rule but people have NO idea how to do this.I have seen this happen myself, but starting from before they became an MPA then seeing the change as is progressed. However similar mental stress occurs in police, military, doctors and dentists. Different stress but all can damage relationships. They all share the "do not bring work home with you rule" however sometimes because of the law and sometimes because of custom.
Worst part is the EGO. EGO says if it is not my idea then it's not a good idea and it can't be real. Until the true pro shows up by magic wand these egotistic nut case see it as their idea. I have worked with people in office / shop floor like this.
I wouldn't marry a SP, MPA, or teacher, they are already damage and if they can't handle the stress, they will get worse. NOW if they agree to do a few things or activities for life to manage their stress, I think I could marry one.
