I don't understand why you keep trying to mend this 'friendship'? They bully you and you keep going back to them. Then they bully you some more. Keep away.

This is not friendship & this Ashley (or even Rachel or Jowita) are not friends.

If you want people to treat you differently, you need to set clear boundaries. If they abuse you, that is not friendship. Keep your distance from such bullies. Otherwise, they/Ashley will keep playing you - one minute you will be friends but she knows she can bully you because you always come back, so she will keep hurting you. Don't give her that power. Don't give anyone that power.
