I think I used to do that as a kid too - to live in fantasy relashipnships with people and daydream all day long. How do I move on after trying all these things?
I'm so sorry you're still hurting so deeply a year later. We all process grief and trauma differently and there are no timelines for healing. There are some here who managed to move on within months of a toxic BPD breakup, while others took years without fully moving on. There's no right or wrong way to grieve.
With that said, here are some milestones of acceptance that helped me move on:
1) This wasn't my fault. My ex was mentally ill and because she refused proper treatment, she beat herself up inside and made poor choices. I couldn't save her from herself and it was never my burden to carry. Although I made mistakes like everyone else in the world, nothing that happened to end the marriage was my fault.
2) My ex was broken inside and made bad choices to temporarily ease the pain. Like any other injury though, a band-aid can only do so much and it won't heal a serious injury. She's spent her entire life riding highs and lows with no idea why, and it will continue until she gets proper treatment. The only true way to reconcile would be for her to fix what's actually broken...her mental health. Accepting anything else is just repeating the broken pattern that caused everyone so much heartache.
3) I am better off without my ex wife in my everyday life. I no longer accept the abuse from her and our relationship works as distant friends who talk every now and then. This realization "freed me" because it allowed me to truly let go of the guilt and shame of a failed marriage.
4) I still love my ex wife as a person, and I want her to find happiness without me. She recently remarried (we separated 2.5 years ago) and I am happy for her, even though I know things will go sideways in that relationship because of points 1 and 2. Still, I hope it works for as long as possible and they enjoy their time together. My kids deserve that and she does as well.
I hope that helped! One other thing I'll mention is that I got back in church after the separation and really focused on my faith. I think that helped me make it through these four realizations much quicker than others, simply because I accepted that there's someone greater in ultimate control.
