This feels messy

I went no contact, but he kept reaching out with 'indirect direct' confusing stuff. The most recent time I asked him if he was trying to talk to me about something and he said no. I set a boundary against friendship, that I was open if he wanted to talk about anything important but to stop sending me casual nonsense. He may well test that. It; been 2.5 months since break up, I think he' s avoidant, could he still come round or will he more likely withdraw further?
