Nah m not married and nowhere near to be either.. still have like 4-6 yrs of my independence with me..luckily.. for the assurance fact u can see it all over the places..I've seen many ppl who does tht and many of my cousins did tht..I don't think any parents will block their children out of their life just because they married someone frm other caste or religion...well purano jamana ko kura vaye aarkai..but I might be wrong too.Ii don't really knw whr u r coming frm and stuff..anyways Best of Luck with u'r life and hope u will make a right decision..
Peace
