I think my ex is still controlling my life even though he's not in it anymore.
How are you going to stop him from controlling your life?
I'm not going to do anything for him anymore.
It can be easy to fall into old habits with a former partner, but it's important not to let them control your life. If your ex is still dictating your life, then you need to cut ties with them completely. If you allow your ex to control your life, you may never be able to move on and find a new, healthy relationship.
I'm going to go to a therapist and get professional help.
That's good! A therapist can help you cope with a breakup.
