Was I dating a coward?

My ex is the type of person to runaway from everything he prays for. He prayed to get into med, got in and left because it was too challenging. He prayed to get into another programme, got in and left and blamed it on me. He prayed for my parents to accept us, they did, and he left and said he hates them for taking too long to accept him (he knew it would take some time, said he'd wait years, they ended up taking 5 months exactly).
Now he has quit university and ran away to his home country and said he will come back once he forgets me and his mind is i the right place. He says me and my parents are the reason his life is so difficult (my parents did nothing but take some time to accept him because they werent sure about him, turns out they were right).

He made me cry, everyday for months and when he knew I was crying, he would block me everywhere and refuse to see me because he didn't like to see me cry and said that I cried to manipulate him. I know realise he was okay with making me cry but not okay to see it because that meant he'd have to look into himself and face his shortcomings.
