Neither I believe nor disbelieve about re-birth (I'd like to reserve re-incarnation for Gods) ..
Just a few days back I and my partner had an argument and as usual we ended up not speaking to each other, just the way my partner likes to end arguments. My partner was at work when I started sending cajoling texts, telling her how much I love etc etc.. And in all my earnest I sent the message "in this life and next if we have one, I'd pray that I'm partnered with you with no changes in our past and future".. I realized I meant it more than 101% and I got a bit emotional at this self-realization!
And that finally broke the silence as I received the response that on another thought my partner thinks that a few points be reconsidered regarding my predicament!
