Those were some pretty scary qualities you listed. You really shouldn't have to put up with any of them - let alone that killer combo. She sounds unsupportive and distrustful, but inspite of that of course you will miss the relationship you had. I'm sure it wasn't all bad. I'm sure you will take some positives away from the time you invested in the relationship.
However - it sounds like you have given this a lot of thought, you're not doing anything rash here. It hurts now - it's an adjustment, they all cause stress - but you will pull through. One day at a time...
I'd urge you to take the time to heal, and then take even more time just for yourself. Do things you like to do, go see things you want to see. It's a great time to take stock of what you want and need out of life.
And if you do choose to head down the relationship path again - you'll be in a great place to start fresh with someone, not to mention completly aware of what you will need from a partner.
I know a lot of friends/co-workers/accquaintences who focus too much on the fact that they are "alone". While I understand the sentiment, I hate to see anyone have this as their one and only focus. (Personally, I enjoy being single).
It hurts now, but that old cliche is true (guess that's why it's cliche?); time heals all wounds. The more time you spend out and away from this relationship the less it will hurt.
You're not alone here. I'm glad you were helped by sharing story (I'm the same way - getting it out of my head by writing it out always helps me). And I hope if you ever need to you'll vent here again.
*hugs*
I'm always up for a shoulder sob too - I'd even let you cop a feel - (that was an attempt to make you laugh by the way). My inbox is always open too ([email protected])
Take care of yourself!
