OK look. The minute your spouse decides to have an A, it means you can't be a part of their life anymore (with the exception of children and business.)
You do NOT allow cake eating. You are better than that. Don't allow yourself to be used and abused that way. If your WS has decided they want to be with OP, then that is THEIR NEW PERSON.
XW asked me for help a few times during our D that was neither business nor kids. One time she came home and thought the house may have been burglarized because the back door was wide open. She wanted me to come and check the house for intruders. I told her to ask her new man for help with that, because that's his job now. Yeah, she lost her sht over the phone and screamed at me about it. Whatever! I hung up. She could have asked OM or even called the cops. Leave me alone.
On several occasions I had to tell her that we are not friends. I am either your husband or I am not, but I am NEVER going to be in your friend zone, EVER. EV. ER.
Also, doing sht for them is not "fighting" for them because they will continue the A no matter what you do for them!!!! They want their cake and they want to eat it too! Every time!
Save yourself. Nobody is coming! BD:11/2017 Filed:12/2017 Final: 2/2018
