I have learned the hard way. My husband and I met when we were both at a traumatic stage in our lives and we were good for each other. We helped each other cope and get back on track, then we had our wonderful son, then we got married.
Now we have parted because we realise that although we love each other as friends, we are no longer "in love" and may never have been. We have our beautiful child and we will stay connected through him but we can both move on and maybe find other partners to love.
