I did great yesterday and today. He has been staying at a friends house for awhile and he came home unexpected and got in bed with me. I told him that wasn't a good idea because we had agreed on seperating and he was shocked and upset. He said he had to go and I told him that was totally fine.
GOOD JOB!!!!!!!
Another good answer can be "I've decided that I really don't want to be with someone who isn't sure they want to be with me right now."
