Need help to save my engagement :(

Why would it look desperate and cheap? A lot of mothers who are friends talk about rishtaas this way, its completely normal in liberal families.

And I've heard that after doing Instikhaara, things happen in such a way that shows you exactly what is good for you. Maybe this is what is good for you.

Let your mom decide, like you said earlier, you should still keep a back seat. If you are really interested in marrying your current fiance then take a stand and be his pillar of support (dont be double-minded), but if you're also unsure, then let your parents decide. Whatever will happen will be for the best. Good luck :)
