Capt,

Sorry you are here but you've come to the right place.

Yeah texting her "how is you day" is definitely pursuit so that should stop immediately. She has filed for divorce so all you can really do is to work on yourself and become the best version of yourself.

Take the focus of her and place it on you and your daughter.

It's highly likely she is having an emotional or physical affair. Any clue who it could be with?
