Anyone else ?

Wondering if anyone has a similar experience...

I was always shy growing up, I only acted like myself around my friends. Till this day I don't dance or sing around my family.

Well my husband and I have been together 7 years and ever since we had kids (4yrs ago) I can't find myself to do that stuff around him either. I'm comfortable in all other aspects but I just can't get myself to sing or dance around him. What's wrong with me? As much as I want to sing my lungs out when he's in the car I just can't and I don't even play my music around him I make him get the aux always.
