Neither of these two sound like promising partners for a healthy relationship. Not sure if it would work for you, but I took a one year moratorium on dating after making very bad choices for years. I did a lot of reflecting during that time and wound up meeting the man I've spent ten years with in a fairly stable/supportive relationship.

Do you think a temporary separation would help at all with the current bf? Make him miss you enough to change or make you realize you don't miss him as much as you thought you would?
