If going out with your ex causes you pain and confusion then don't do it. And I would seriously consider dating, not to start a new R but to boost your confidence. Or simply go to a meetup group (you can google local ones) and start hanging out with others hiking, salsa, whatever. There is a DBer on here who believes in the philosophy that the easiest way to draw back your spouse is to look like you are desirable. So even if you aren't dating kind of hint that you are. Be mysterious, if she asks what you are doing then just say, hanging out with someone. Nothing more. When you talk to her be busy, busy , busy. End the convo before she does, stop hanging on for her.
