Bless you Monica. We are all trained to use band aids. "Smile/Be happy/Cheer up" and we know they don't work, because LOA responds to our feelings, not our words.
Personally, I would let go of the oxytocin thing, it only gives you an excuse to be where you are :-)
This is not a quick fix process, but will help you clear up a lot of blocks. In 1 month, it will change all your vibrations on this matter of relationships.
