How much togetherness should a couple have?

My bf and I have always been very good about having our own individual interests and activities. But before the separation, we did more things together. (We we’re separated for four years, and about three months ago, decided to try to get back together.)

This morning, he went to the museum without asking me if I wanted to go.

I’m a little hurt. But:

1 - He was always more heavily into the museum than I am. It was always more “his” than “ours” or “mine.”

2 - He does do things together with me. A few nights ago he took me out to dinner. Last night he took me to see “Rocketman.”

3 - I do things without him. Every week I go to a knitting group without him. Once a month I go to a book group without him.

I’m not sure how I should feel about this.
