im from a dog sign so as my partner.we quarrel almost everyday because of difference in opinion.

Im a cancerian too apart from being born in the dog year.My boyfriend cheats a lot of things. He make use of my wealth. he will do just anything for his friends's need including forcing me to help his friends. I have tried for breakups but i feel pity for him as he pleads never to do such and will change but he repeats. my nature as a cancerian never allows me to do something drastic. he too blackmails me to hurt himself if i leave him. Our marriage is fixed by the end of this year. Can u tell whether he will change into a good person and i wil lead a happy marriage life? quarell
