This is a great point. A couple did this to me during COVID, and it was actually mainly the woman in the relationship, and it was really awful when she started withdrawing and not getting back to me for days to weeks when she had just said she loved me and that she also wanted to be my best friend. It triggered massive limerence in me and anxiety, because of the love bombing that they did to me at the start. Now I realise that ultimately their main relationship was DEEPLY flawed and actually abusive. And I was probably a distraction from that.
