To be honest, I DO feel crazy. It's all so complicate and messy. I oscilate between hating him and wishing we had never met and wanting to make things right for my part in it.
So in a one-year relationship, he:
- Lied to you many times
- Lied about you to others
- Cheated on you (many times)
- Was hospitalized for mental issues
- Found a new love (in an old flame)
- Lied to her about you
- Lied to you about her
- Showed no remorse or appreciation
- Avoided you after helping him
That list is just from two of your posts, so I'm guessing it's only a small snapshot of the full picture.
Going back to your first post- what part of that list makes sense to anyone? It just doesn't. And it will never make any sense until you add the one thing that all of this revolves around. He's sick. He's mentally ill. He means well but self-sabotages every relationship in his life. Then he runs before he can get hurt. But it still hurts, so he jumps head-first into another relationship right away.
This is the story of a BPDs life. It's the same toxic, abusive cycle. And its heartbreaking because I'm sure underneath the mental illness, he's a pretty good guy. But you can't look at one thing without the other- they're a group package that comes together. That's why his past relationships have failed. That's why his future relationships will fail. It's sad but unfortunately, it's the honest truth. He's sick and he's the only one that can help himself.
You are not crazy and this is not your fault. There's nothing you can do right now to "fix this."
I will give a piece of advice though; his current relationship will also fail and he'll be looking for someone to quickly replace her with. He might come back and say all the right things, do all the right stuff, and you'll think that it's true love destiny that you're together forever. But the same cycle will repeat once again, just like it always has in his life. You'll have a whole new list like the one above.
Right now, your focus should be on healing from this relationship and finding your way forward. It doesn't make sense right now because this comes in stages, but I'm telling you now where you'll eventually end up- he's mentally ill and none of this was personal. He does the best he can while fighting mental illness and it causes chaos in all his close relationships. That's not your fault and in some ways, it's not his either. Again, he's sick.
I hope that helps!
