I do not want to do with my parents’ “advices”

My story is a little long and more I do because I do not speak much English but here goes.

My parents have always been very overproductive with me and they did not let me have a boyfriend, until one day I fell in love with a person ten years older than me and I left with that person unexpectedly, we got married and now we have a little girl of two months; Anyway, my parents can not take it with my husband after all that happened as they can not close the wound because it happened a year ago, besides, I'm tired of being told that if having a girl is not a game, that is going to cost you money and things like that of work and effort (something I already know and I do not need to be told), above all, they put an intense and stressful tone on those economic issues that I really do not know how to tell them that They bother me with those things because I know what I got into and the responsibilities a baby carries. help.
