Cutting the ties. That phrase always reminds me of cutting the umbilical cord. I know this is gonna sound odd but do you have a younger brother or sister that came along and I dunno, to a child would that make the child feel like the Mother no longer desired you. That you weren't good enough. Sorry if that sounds really strange but could you be repeating the cycle in your adult life stemming from something that happened way back to a time you can't consciously recall. There's just so many variables and by that I mean it may not be a younger sibling, I guess it could be anyone that you feel your mother was more attached to but that stuff is hard to pinpoint when we're all grown up and always on the lookout to see who is attracted to us in the present rather than what took place in the subconscious in the past. Have you tried hypnosis?
