Sudden spike in bounce rate/page loading issues

Site URL: https://foliagenashville.com/

Hi all! I'm having some serious issues with Bounce rate/site loading issues lately. In early Jan. I'd worked really hard to get my bounce rate average down from 70% to about 40%. Then at end of Jan. suddenly it shot up to 80% and I can't get it back down. I've been trying to figure out the reason, Google Analytics says scripts running, etc. but I don't really have much custom coding if any going on. Would LOVE some help, cause it's seriously affecting my conversions lately.
