Hi ,hvert
It is unfair and tiresome to go through it every year ,sorry.
I always remember mothers/Father's Day to do something,but I suppose I'm not good enough to be remembered ,despite having 3kids:my husband took off with his friend to see a hockey games out of state for few days,didn't even remember to call,and this year is not an exclusion .just live your life,don't take it close to your heart,you will not change her or her ways ,don't let it bring you down ,she is battling her own monsters .
All the best to you!
