Don't get it??

I really am having a hard time trying to understand why one blocks you mid conversation. Someone texts you and gives you positive feed back and loves and expresses they have the same interests and belong to your same groups. They share their interest and desire. You share yours and you both are on the same page. Then BAM. YOUR BLOCKED. Why waste the time to chat if you truly were not interested or had ulterior motives. Just be honest. How hard is that.
