Someone once posted to me that "trying was one thing, but trying with the expectation that "A" will result with "B" is a recipie for disaster."
It's amazing how much heartbreak hurts and effects us. I lost 20 lbs in this whole mess (might market that one)! I felt completely out of control of my emotions (still do from time to time). I seriously thought I'd die from it. It's a trauma. You're living through a traumatic experience. You'll probably carry scars from it and it may spring up in your memory from time to time, but you don't have to let it define who you are.
No one is perfect and no marriage is perfect. It's hard and you stumble from time to time. It's also a partnership and if he won't be a partner, then find someone who will. Don't give up on me now. We're the same age and I believe this isn't the end for either of us.
STAY POSTIVIE! YOU'RE DOING GREAT!!
When you are happy as an individual, you are in a better position to determine whether a partner enhances your happy life or weighs it down.
