I'm thinking about confronting her about this. Since she's clearly looking for a date, less than four months after we split, and we aren't even divorced yet.
First of all, sit on this for 48 hrs and then decide if it is still a good idea, or something that you think will bring you closer to your goals. And the latter is the big issue here -- how is confronting her going to help you? You pointing fingers at her, trying to make her feel guilty, being the "right-sayer", etc, is honestly going to accomplish nothing IMO. She's going to have to work through this on her own and battle with her own demons. Don't you think she knows what she's doing? Don't play the father role in telling her what's right and wrong, okay and not okay, etc. It will only push her further away. It is a control behavior. You must let her make these choices, live the consequences, and decide on her own that she made and is making a mistake. If you try to control this process, it will either only prolong this understanding or prohibit it altogether.
