I'm back again 4 years later

[praying_in_GA]

Backstory: I work the night shift as an RN three 12 hour shifts per week. He is a full time nursing student.

So, this morning I got home and he was getting ready to leave for his final exam. We chatted about his haircut and his final today. I asked him if he still wanted to take the kids hiking this weekend since it was supposed to be nice. I mentioned that he need not feel obligated and that I would take them out to do something if he had "beginning of spring break" plans. He said he would still like to go or maybe we could take them bowling. He rubbed his hand across my shoulders a couple of times and said he would see me this afternoon.

Conversations are so easy going between us. There is no hatred or animosity. He just feels as though we make great friends. The spark is gone. The butterflies in our life have fled.

Is it wrong to chat with him like we always did?

He has been wanting a motorcycle forever. I have been very resistant to the idea due to my father being killed on one. He has been searching for sale ads frequently recently. Is this something I should engage in? I am fine with him getting one if that is something in his life to make him happy. If it is between him having a bike and him wanting to go by all means, get the bike! He leaves the page up for me to see. Should I mention to him that I hope he finds a good one or I would like to learn to ride it (honestly, I would)?

How do I interact with him? He is still wearing his wedding band. Do I detach and only communicate when it is in direct discussion of the day to day household / kids? Or, do I engage in casual banter while leaving out talks of R or M or anything related?

Please help. I feel alone in this and I want to know I am doing the right things.
