nodaybut2day, good advice that I agree with. Al-Anon can be a life saver and will give you tools you need to work your recovery and begin to heal.
When you have the urge to call or text you don't have to say no, try saying why instead. Be honest and think about all the reasons you are not together. That worked for me although sometimes I had to force my self not to call and tell her what I thought, but that's a different issue.
Your friend,
