My brother-in-law and his wife has life so messed up. They want my youngest son to come out to California with his Mother, my Mother-in-law to visit with them.. They have said so much evil things about my son, me ect.I dont trust them, dont talk to them, and dont like them.. then they had the nerve to not ask me or my hunband (my sons father), but asked my Mother-in-law like she has custody or something. My kids will never go hundreds of miles away without there Mother or Father being there plan and simple.. Lord help me and them, i dont want to have to go off on nobody.
