Let’s face it, no one wants to deal with a partner’s ex. Unfortunately, there are instances where interaction with the ex is inevitable, especially if they share children. It would be nice if everyone involved could just get along, or at least be civil – but we all know that isn’t always the case. Sometimes women are just mad that there is an ex in the picture, so immaturity may be the reason a woman doesn’t like her man’s ex – especially if she’s done nothing to you. But if you feel that his ex is up to no good, watch out for these signs that may indicate that not only is she not over him, but looking to wreck your relationship as well.
