Why?

I don’t want to be alone if anything wrong happens overseas

So, you’re the one who is travelling not the other partner?

What if the partner betrays?

Before making the decision, you would obviously go with all sorts of experiments and experiences with your partner. So, here the probability for getting betrayal goes significantly low. But even with a 0.5, you can’t assure the future. Now, if the partner betrays you there in the new land, the core thing would be moving on and starting alone.

Also, betrayal is same with the international and the internal territories. It depends on how you cope up.

There have been worst cases in the past what ive heard
So if i were to take a decision I wouldn’t prefer marrying anyone abroad
And i have talked to indians in other countries not everyone has the right mindset most of them are there for money

I don’t want to be alone if anything wrong happens
I have never said betrayals wont happen in india

Make sense, thanks!
