Hey Bunk,
I really feel bad for you to have gone through so much, it sounds exhausting and crazy making.
As to the letter, a big NO on sending it...but a big YES for writing it. Write another. Then Write one to her and tell her how you feel what's it's been like to be with her, then be without her, all the BS she has pulled and how that made you feel and then how you feel now that you've been away from her for awhile and if there is less emotional drama in your life.
This is NOT to be Mailed either.
It's for you to really get all this out. Believe me, it's very theraputic to just get it out. What I like to do with these letters, that sometimes have rips in them from the pen pushed so hard through 5 pages and wet with tears, is that when I am done. I fold it all up and then rip the shit out of it, tiny enough to flush down the toilet where it belongs or if your lucky you have a fire place and you can watch it burn.
Then You are going to have to get into some type of recovery mode or you will repeat this with another girl. I didn't beleive this. I thought I learned mylesson, I even read books about the disorder so I knew all about them, but over a ten year period with 3 guys they were all crazy one after another and next thing you know I'm in my 40's and it sucked real bad, went into a bad depression.
What got me out was using EFT for my emotional upsets and going to support meetings (for me I chose Alanon because it's easier to find a meeting and they are experts with dealing with difficult people and teaching you to put the focus on You instead.)
And then it (you ) your life, can really, really get better. I've been engaged to my soulmate for about 2 years now as a Direct result of using EFT and Recovery for several months.
I feel your pain and want you to know you are not alone andd all your feelings are normal, you just got to get them out.
Take Care of You, your worth it, you sound like a really nice guy.
I hope this helps.
