No, sweetheart…you have to do some compromising here. I remember you felt a bit confused about your cousin. If you reject him…your parents will get upset. Instead…be honest with them by CALMLY telling them that while you don’t feel attracted to him and while he’s not what you had in mind…you’re willing to get to know him…although that isn’t a guarantee that you’ll say yes. They may feel a bit relaxed that you’re willing to get to know him.
^I understand that your parents really like him, but I doubt that they would want you to be stuck in a life-time of misery. Is it worth brining them only a few months of happiness (by saying yes to the rishta)…and then being miserable the rest of your life…or perhaps (God Forbid) end up with a divorce? Is that a reasonable bargain? A few months of bliss for a life time of frustration? Should your parents put the time/effort/MONEY into arranging a wedding where their own daughter isn’t happy? Is that fair to your parents? Is it fair to the guy and his family?
^Be honest about your feelings…but say you’ll try to get to know him…and tell them that getting to know him might mean a rejection if you don’t find him compatible.
******************OTHER SUGGESTION: Try talking to the guy (your cousin). Is he someone you can trust? Maybe you can explain to him that you’re not interested and you feel like you’re being pressured by parents. Maybe he might help you out by rejecting the rishta himself FIRST. And if he rejects FIRST…that clears the way for you.
