@inmyshoos I so feel for you! It's unbearable sometimes especially when things could be so simple and wonderful and there is no reason on paper why two people who adore each other and match perfectly can't have a lovely life together.
Believe me, I understand. I don't have much time right now, and am on my phone, but my case I have been on this (what feels like) never-ending roller coaster for 4 years and it's complicated by the fact that we work together. I have also been married before and have a 10-year-old daughter. My marriage wasn't great and I left my ex-husband many years ago and was very happily single.
Then I unexpectedly changed jobs and met him. Honestly if before we met I had made a list of everything I loved in a man - it would be him to a T! He was beautiful inside and out, we clicked on absolutely every possible level and could not have been more perfectly matched. The connection between us was so deep that it was almost unconditional love that was inexplicable. We spent all day together at work and then on average 5-7 hours every day outside of work - just talking about anything. I've been in relationships before obviously but have never felt such a deep soulful connection to anyone.
However, a combination of childhood trauma and a difficult break up (many years ago) caused him MH issues/severe anxiety that I now no longer believe we can overcome together. It's like having two people - this beautiful soulmate with a kind soft nature who understands me without words and then this mean, horrid selfish stranger who runs away from life and is unable to function like a normal human being.
The good times between us were so good that I was prepared to forgive and forget all the hurt, tears and disappointment he caused me. But over the years, due to his refusal to get professional help (again out of anxiety and at times denial) and a combination of me always being there for him/too soft and gentle in him - things just got worse. The good times decreased and the bad increased. It was one day good - three weeks (or more) bad and I became almost like an abused carer for a severely ill person.
It still completely breaks my heart, but I have made a conscious decision to stand back and no longer provide a "safety net" for him. I am hoping (although don't have anything positive to report yet) that this will push him to actually get help and make an effort to get better. It's incredibly difficult, as I see him every day at work and am so tempted to just go back to the "old times". But I have finally decided that unless he is willing to pull himself out of this darkness- there's just nothing more I can do.
