How to deal with over possessive Taurus mother?

Well she may just take so much pride with you that she gets over protective without realizing. A taurus takes pride in things that they have and love to keep them. Try calmly telling you how you feel. Taurus likes their personal space so tell her that as much as you love her you feel that sometimes your space is taken over. That may hurt her since a taurus is very sensetive but she'll get over it.
