Well dear, that choice is yours alone to make. No other person would be sharing the consequences of whatever decision you take, so do not let someone else make it for you since you'd rather live regretting your own mistake than someone else's, right??
Families/parents are so fond of comparing and contrasting when it comes to life issues like marriage. They'll remind you of "Aunty Stella" who did this and that happened or of "Uncle John" who went this way and that way so on.
The truth is no two people's destiny are the same, they might turn out with the same outcome or not. But absolutely no one knows what the outcome is yet until you've tried. Your relatives are just taking precautions of which might turn out true or false.
At the end of the day, its left for you to choose between the partner you want or please your family members. If you do the latter, will you regret it in future when all the "what ifs" arise??
If you choose the first, can you stand your family and their dissapproval??
Now is when i'll tell you to search as deep as your soul can go and make a priority check?? which can you live with?

Love is a strong thing, it overcomes a lot but it also has its share of risks and challenges, are you willing take them??
