Whats love got to do with it? Everything yet love does not mean a relationship is meant to last.
Have you seen the movie La La Land? sometimes relationships are not meant for that ending we might have imagined. Fate Destiny… and or does Life demand that we grow of which relationships are a tool, and that sometimes the lessons we need to learn will only be looked for through the pain of a relationship ending. I do not understand why this is so, why we can’t learn our lessons when life is as we imagined, but for most people we are like a young bird that needs to be pushed out of the nest.
I found the following book helpful when I asked similar questions to those you are asking yourself.
‘How to Be an Adult in Relationships: The Five Keys to Mindful Loving’ by David Richo
