FA’s/DA’s: What is your process when stonewalling?

I’m an AP with FA leaning and I dated a DA who could stonewall me for weeks on end. Even when I wasn’t engaging in protest behavior and giving a few days of no contact, he could go for a week with absolutely nothing. Of course, sometimes I would engage in protest behavior and compulsively text. Once I got in a bike accident while we were fighting and he wouldn’t respond when I was in the hospital. I know this is a deactivating strategy for DA’s but as an AP, I just can’t fathom ignoring someone when they’re really really struggling and curious as to what your internal process is?
