So taking away the burden of specific outcomes and just keep doing whatever may be our actions as matter of duty is way to free up ourselves from stress and anxiety that comes when outcomes don’t meet our expectations..
It’s perfectly alright to expect the things to turn out in certain ways but it’s another thing to be attached to expectations of those outcomes ..
We are tiny creatures in grand scheme of world around us… accepting it and finding something to be grateful for in our everyday life is way to go IMO..
New partners will be found, new relationships will be developed, things can be studied/ researched for whole life .. what matters most in this moment to be able to acknowledge that we have very little control over things around us and being grateful for whatever we have in our life..
I found Bhagavad Gita to be very empowering.. May be you will as well ..
Good luck !
