Husband called me a liar..

I got this paper in the mail today, essentially saying I need to get in contact with gym people as it’s still showing I owe a balance of $288. I called months ago after I lost my job and let them know I couldn’t afford it anymore and the guy I spoke with said he would note my account and get it started. Never heard anything back.

Fast forward, got this paper saying to reach out, husband calls them mad because I never even used the membership- irrelevant because I still signed up- and demands to speak to manager. I don’t know what transpired on this call, I went with our toddler to get a craving I have had (14 weeks pregnant and finally able to start eating something) and before I got home, he texted me calling me a liar. Pulled up to house, he’s standing outside waiting for me like he’s about to take off with our toddler and leave me there. Talking about how I lied and never talked to them- I most certainly did but that they told him I could go fill out paperwork to cancel tomorrow and possibly not worry about the $288. Ok, fine. He then blows up on me, saying how it’s my fault we take 1 step forward and 4 back, that he doesn’t believe in me and starts threatening and walking out of our house to spend the night at his parents house. Over something that’s entirely my ordeal and only $288 to begin with that I thought I took care of months ago. He did this stuff when I worked too, it was never enough, I didn’t contribute enough even though I worked full time at home, watched our baby at the time full time at home, maintained our home, cooked meals, the whole 9. He didn’t lift a finger and still doesn’t except to pick up his fork at dinner time- I literally fix him his plate every night and bring it to him or if he’s working in the garage. I’m bawling my eyes out, it feels like my own husband isn’t even on my side and I’m trying hard not to have a panic attack while he’s trying to walk out on us as a family. All while our toddler is watching my cry, begging him to just talk to me and not leave.
