... but just don't know how?
(NC for this as I'm shy(
I have a good relationship with DH, been together for 20 years, married 17, 3 children. He really is my other half, best friend, supportive, makes me laugh and we work well together when there are challenges like money, family etc. So no major disagreements or problems, this is not an LTB post 
Our sex life is also good. We do improvise and play games (just the two of us) and we have fun together.
It's just that after 20 years, it seems that there is no more anticipation, or excitement or spark iyswim? and not sexually speaking.
For example, we can drive for an hour or two without saying a word to each other, perfectly happy listening to music. Whereas in the beginning we couldn't stop talking. There was always something to be discovered.
I don't mean we're bored, just that it's so different. I want to feel like we're dating again. we sometimes talk about it and usually conclude that this must be what it feels like being in a long term loving relationship.
AIBU to think that we can bring back this spark? or am I just having a mid life crisis
