Re: What should I do? 
Well, the elders in his family called your mother and ended any further rishta talks. The guy has told you already that the final decision will be made by elders. You still can’t figure out what his decision is?
Oh and btw, in an arranged situation, you should not be texting for WEEKS. Pick up the phone and actually TALK. Have 2-3 long conversations that are straight to the point. Discuss future goals, expectations from spouse, religious practices, concerns regarding joint family living/career/education etc. Then give your family the green light to move forward OR end things.
Once engagement happens, then continue to get to know one another by texting or whatever. But this is not a dating scenario where you’re going to exchange text messages for weeks/months before baat paaki. B/C if you do, then you risk happening what you’re going through now…getting emotionally attached to a guy who has made absolutely no commitment to you.
