Festival Life Might End My Marriage

I'm a 42f, who is married to a 43m, and we have been together for 18 years. We got married 9 years ago, and we have a great life together. He works hard to put food on the table and provide us with luxuries and the ability to travel the world together. 

I became interested in the festival scene around 2013 where I first experienced MDMA. Needless to say, the combination was ephoric, and I had the best time of my life.  Over the years, I continued to attend festivals and actually started going to more and more as the years went on.

The problem is, my husband is not into EDM and won't experiment with MDMA.  At this point in my life, I just don't feel connected with him anymore. I feel most connected and loved when I attend these festivals, and when I get home, I just don't have that feeling. 

Am I crazy for thinking about leaving my husband? He's given me a life most people would die for, and he is the most loyal, loving, attractive, funny man I've ever met.  I just don't feel connected to him anymore.

Has anyone been at this crossroads before?
