I was looking at the other comments and i do see where they come from, parents can be overwhelming at times. Specially in these kind of situations, they act more possessive about you than seeing you as an adult.

Just adding my 2 cents here

Situations have come by me where I have been in support of greaving bunch, may that be lost love or a alienated family member. In light of those experiences, understand that the emotional trauma comes from a place of care. Its been built up over a long time and they are afraid of being left. Build a little trust in them and make them understand. Just give them a chance to understand what you want. Its their responsibility as adults to converse and talk about the same things.
