I hope this helps..
Im 2 months on from breaking up with my XAH.
Like you at one stage I was basically obsessed with her. There will come a time where you and only you can decide its not worth it.
I basically saved my partners life, did everything to give her a fresh start (3 month rehab) only to relapse 5 months later. Never a word of thanks all hard work.
Its tough but no contact is the only way. As someone told me I got myself into this I need to get myself out. Everyday I get better, the pain is still there but also the realisation I deserve more.
You deserve more , he will never change . BELIEVE
The sun will shine again. Take cAre
