Consulting one's family regarding a proposal

My family had got a proposal for me and I was interested but with no solid reason my father refused. He said things like, the boy's family were living far away, and also he is 10 years older then me. I did istikhara many times and I got no negative signs. I do pray daily to turn my heart away from this but it is uncontrollable now. I want advice whether I should ask my family to consider it. I'm afraid that once it mustn't get refused for a reason that is not valid.
