Wife wants to separate at end of school year

[Bhuda1]

I am not acting cold at all. I am just not having any physical contact. No kiss goodbye or goodnight. Some nights I do not even say good night where as I always did in the past.
I feel she may have had second thoughts of suggesting we go our separate ways in June as she mentions possible future plans for camping as a family and other events in the future. I would like to have some sort of discussion about our marriage because I feel better equipped in handling any negative reaction she may have. This due to reading DR.
We are getting along, and we talk about everything , except our relationship. My 180 has been no kissing goodbye or goodnight, not being ready to drop everything to accommodate her schedule while totally rescheduling my day. As I typed this I realized my 180 needs more work
