Is my ex playing with me ?

Ok too long story , i cut it short .. My bf broke up with me two years ago. He broke all his promises of marrying me because his parents weren't agree for him to marry me so he couldn't go against his dad.
Then he also deleted me off his fb account as a result when he texted me n i didn't reply him.
later on i was dying without him so i added him again n continued a sort of friendship with him. I always compromised n invested more than him n he used to chase after my female friend (who was also his friend but she left him as he left me, so he tried his best to regain his lost friendship with her)

On the other hand i cared for him , loved him but he took me as an option without realizing how much he hurts me. I was the onw who used to text him more , chasing after him ,
Now i have stopped texting him n chasing him , so he now texts me after 10 days or after two weeks n just asks me how i am etc n sometimes like y i haven't texted him at all , where i am ..

Now question is if i am an option for him then y he texts me n asks me when i don't txt him ?/

Does he really care for me or what ??

Recently on my birthday he wished me by saying "U ARE THE SWEETEST GIRL "
what's this ?? y he is trying to be nicer to me , is he just having some fun at my expense or what ?

He says he cares for me but his actions are opposite

Is he using me ??
