Thank you AS, Joe and Helpme for your suggestions.
I wrote "Yes, I will keep our D". To which she replied "Thank you".
I know AS that whom she is spending time with should not matter, but it's just that you trusted someone with your life and dreams and what you got was betrayal.It hurts to see that they think their selfishness is above family. Our D who is just 2 does not understand what is happening and when she does, the pain that I have today will be compounded and my helplessness in not giving my child what she deserved in terms of a complete family like other kids will bite me in the face. Just venting.
