Should i move or should i stay?

Sounds to me that he is unreliable and untrustworthy. If I was in your state of mind, I wouldn't chase love. After all it seems that he doesn't wholeheartedly love you. You should stay where you are and try to create a better relationship with your mom. If you and your mom talk things out in a manner-some way, I am sure things should work out. Think of your child. . . you need safety and security and protection. You also need a stable environment.
