Oh dear, I'm going to cry too...that's so sad and I'm so sorry for you...but good for you that you have a wonderful guy in your life....most of us are struggling to find one....so cherish your current love...because you don't want to lose him!
It looks like he was the first love of your life, probably that's why still hurts...and you feel for your daughter too...
just try to not think about it....I personally found out if I quite all contacts with the person then I will forget all about him....but I know it's difficult in your case, because of your daughter...
Crying is good for you....You should cry it out till you don't feel anything anymore.....keep a positive attitude and focus on your love, you will be fine...time is the best healer
take care of yourself
