It may be that there is a problem with the idea of reincarnation. Most religions that assert it do so in combination with the idea of karma. It would seem that the idea of advancement (reincarnation) would be frustrated by the idea of keeping things balanced (karma). One can see the attraction of a life that would be easier. However, when you look at people throughout history who did have it easier, most did not turn out well. H.G. Wells in his outline of history book asked the reader to try to excuse the Caesars by asking the reader to consider how he would have turned out is every wish he had since being a child was instantly fulfilled.
The communion that you seek might be found by those of us who have had to face difficulties and as a result come to a point where we can let go of some of our natural selfishness. The key in this life is to navigate around those who would inflict their selfishness on us and find those who have come to abandon some of their own and are now capable of connecting with others with the selflessness of love.
For me this path was from an abusive home through the drug life of the late 1960s and early 1970s. I began to look into the religion in which I was raised and had to navigate around the thousand ways it was so poorly presented. I found at the core that of value. I didn't marry until I was 43. Since then life has gotten better and better every day for over 30 years now. I feel sad that my parents never knew the reality of the religion they professed.
I put up a web site with various observations (
http://christianpioneer.com/ ) I had over the years about Christianity and how it came to be so poorly practiced. I was my thought that maybe some others would find value in it and not spend so much time as I did trying to put the pieces together, However, if life had been easier I know I would not have made the progress I have.
I hope you are able to find the communion you long for in this life. I can testify that it is possible. Love is not always an illusion, it can be found in the abandonment of selfishness. This transition is what I discovered at the core of Christianity, but it was hard to sift through all the baloney.
