He blocked me on everything suddenly once and I chased begging him to unblock for days which worked. The second time he blocked me I learned to not do that and blocked him right back. He then unblocked on his own 2 weeks later and then I unblocked a week after that. By 4th week, he texted me first and opened communication again. Currently blocked again for 7 weeks so far and i blocked him back this week finally. No contact is forever for me until he reaches out first begging to reconcile.
