There are lots of things you can do together, out of the house, that don't have to be in groups. My ex and I used to, for example:
picnic in the park - for no special reason
go for long walks around the neighborhood (we used to walk our dog together)
go to the beach (or lake or river)... late at night! We used to put our beach chairs
in the surf and have long, deep conversations. Once, we lost track of time and didn't get home until close to 3AM!
Drive - and play your own version of
carpool karaoke (our rules were that we got to pick our
own songs on the way there, but pick
each other's songs on the ride home!)
if you're into it, play a board-game or card game together (David loved to play Uno!)
we had a
noisy and
busy household (6 of my kids lived with us!) - so, sometimes we'd get fast food and just park somewhere... stay in the car and eat our meal with
just us...
I don't know if you live (or sleep) together, but for David and I, we never
ever - even in the midst of fights - went to bed without saying
I LOVE YOU (although it was sometimes:
I still love you!). Additionally, we never left the house without saying goodbye and I love you....
