How to approach W about OM

[OfficerInNeed]

I have reached out to her father. I invited him over for dinner as a surprise for her but she was not impressed. I spoke to him about this matter a few times already one-on-one. He said ultimately it is up to me and her to work this out, but if one wants it the oter does not then you have to accept it. He also said "Look at me and her mother we divorced and we are as happy now as we were ever before." He is pro divorce.

My W accepted my offer to a movie then later changed her mind and declined. I was cool with it. We had a couple movies that needed to be returned to blockbuster and she said she wanted to go for a ride and she would return the movies in the process. She left and then I went to work. About 1hr 1/2 later she txt me a picture of our dog in a funny position, which was confirmation she had returned home.

My W still txt me in the morning that she is leaving for work and again when she arrived at work...for example
- "leaving for work now"
- "made it to work safe"

Do I reply to these messages?

I already made a few mistakes. I offered to go out and get her food and I got the shoulder shrug in return. I also ran to different parts of the home to retrieve items for her. I am trying to detach but I am not sure what is good and what is not. Such as the text messaging. I wont initiate convo with her but if she does with me should I always respond?
