How is he using you if your only contact between each other is text based?
BTW: What country do you live in? Or what century do you live in? I suspect you don't live in either the 21st century or a developed country if "[h]e broke all his promises of marrying me because his parents weren't [sic] agree for him to marry me so he couldn't go against his dad.
If you lived in a western country during our present time? His parents shouldn't be taken into account.
As far as his behavior (texted only)? It's not much of a commitment to text someone niceties.
He says he cares for me but his actions are opposite
What actions? Texting involves little to no action at all. He could be missing you but this level of involvement isn't that strong enough to consider he's still that romantically inclined with you. Move on and find someone who isn't a slave to his parents' every wish.
