hi lulu,
The silent treatment and being ignored is surely something that is painful ! And being in such a relationship can be very depressing.
But don’t worry … you just have to take your mind off that relationship and find some hobby or some other better purpose in your life.
I have been through similar situations. You just need to distract yourself and focus your mind on something else … slowly slowly things get better and you will start to heal completely !
Speaking about relationship any relationship that doesn’t make you feel happy is not worth having … love yourself enough to walk away and your life will reward you with new relationships where there is more love and care !
World is filled with so many loving people … you will surely find people who will care about you and love you !
