I need some help with my parents?

Your mom Is probably feeling the same way about you. The way you chose your father over her, is why she is choosing her boyfriend instead if you. I would say just give it time; if you mom is a great mom she will realize that she is hurting the relationship.between the two of you, and as a result making you runaway from the connection y'all once had. This goes agains human nature between mother and child, and sooner or later she will come through. Right now your mom is feeling a bit selfish, but isn't everyone at some point. She doesnt realize how difficult it probably was for you to choose to live with your dad, nor what you have been going through in this point of your life. All she cares about is herself and her emotions and how you hurt her. She isn't being the bigger person, the adult. Give her time to realize that she needs you, as well as let her realize that you need her.
