Lena, I am sorry it didn't work out.
You did what you thought was best for you at the time. It's all anyone can do.
Now it's time to focus on your healing and moving forward. The stickies at the top of the main Relationship board can give you a lot of good advice and tips to help you move forward.
Remember that we are here to give more advice and support or need to rant.
Good luck. :)
