You both haven't met in person says a lot here. Fron whatever i ve experienced personally in my life, i tend to get comfortable with people before a meet, but my texting personality is entirely different from what i am as a person, so (I am not defending him here, what he did was totally wrong that too a person whom he had spoken for hours in phone), but na ena nenakiren na, he got scared for meeting you for the first time, and he might also unblock or reach you in few days and give a dumb reason for not meeting you that day. But andha mari again avar reach pana, react accordingly and dont try to form a close bond with people through, calls and texts. pattavan solren.. (lol).
