I guess that's kinda what it boils down to. She traumatized you. That's pretty big in my book.
She's said she's doing better. Did her shrink take her off her meds or did she just stop taking them? I mean.... It took 3 months of stepping my dosage down to get off mine and my shrink took me off them because HE and i both felt I didn't need them anymore. Most psych meds say don't stop taking them without your doctor. There's a reason for that cuz of withdrawal symptoms that can even include psychotic episodes. (They usually don't give an explanation as to why you need to discuss that with your doctor)
Ask yourself this. What, besides the 2 years, do you really have invested with this woman? Are there kids, financial investments, property? If you leave what are you truly losing? You love her enough to marry her but is that her or the idea of her.... The person you see behind her pain?
In life you must, to some extent, be selfish. It's psychologically healthy to be selfish to a point. What makes you happy? Where do you want to be? What benefits, strengths, security and balance does she offer you? Will she help you to achieve your goals in life? Is she supportive of you? Do you like the person you are with her? Answering these questions to yourself is the exact type of selfishness that is healthy. It seems there's a lot in it for her but what's in it for you?
The old saying " there's plenty of fish in the sea " is true. The key to marital bliss is full focus on you. Your needs, your wants, your direction, your belief system and your happiness. Me me me me me. I was lucky enough to find that with my wife. What it took to find that was full focus on what I wanted in my life. My personal life... Me... Mine.
I dated A LOT of women (30+) between my divorce and marriage. But.... By switching my focus onto me I didn't end up wasting years and years of my life with them. Save Kelly, my abuser, I think I just got tired of looking and settled. Obviously don't settle cuz it was a totally waste of 3 years of my life and took a year of therapy to get over her abuse. Like I hadn't had enough in my life before I met her lmao.
You have to look back to look forward though. What did I gain from being with her and what positive lasting effect can I glean from that nightmare? In able to help you
