(((yeliab12))) - I can certainly see where this lack of trust and self doubt comes from. Do you have access to get some counseling, since this would help the most. So sorry for your family experience and the abusive relationship. Therapy will teach you healthier relationship patterns so you're not filled with self doubt.

How old are you and you still live with your mom? Best thing for you to do is - make sure you finish your education or take additional training so you can be independent and never taken advantage of. The best person for you to depend on is yourself and a partner is a bonus. I hope it gets better for you.
