After 3 years bf says we mismathc? why he was asking me to wait then?

my bf hid that his parents and brother were charged under Dowry case by brother's wife. And he made me wait for 1 year by saying that we wud marry once brother;s divorce settled. We had seeing each other for 3 yrs now. And on insisting him to give me a definite time of marriae, even if its end of this year or next year, but to give a Definite time frame....he broke-up saying he ddnt think we matched! Then why kept me waiting? Did he not see mismatch before?
