basically I thought I had healthy enough stack to not risk a coinflip or possible domination to BB showing significant strength. was it wrong of me to fold?

Thoughts like "not risking a coinflip" are not going to get you the big money. Put your opponent on a range and decide if you are ahead or behind.
