Trauma bonding is so crazy. No contact is the only way to get over it. The longer you go without seeing or talking to (or even about) the abuser the more your sanity will be restored. You are not thinking clearly because your emotions have been tampered with in a bad way. Just stay away. The person has mental problems you can't fix. Just work on yourself. The stronger you become the less chance of this happening again. You also need to gain knowledge about trauma bonding.
