Being badmouthed by your ex can affect you on a couple of levels.
On the one hand, you may be resentful and angry that your ex is criticising you at all. There may be all kinds of feelings left over from your relationship and you find yourself becoming extremely emotional when it comes to things they say and do.
And on the other, the fact that this criticism is being directed via your children may make you worried that they’ll be turned against you – that whatever your ex is saying will get through to them and they’ll begin to view you as your ex does.
Sadly, it’s a situation faced by lots of ex-partners. But quite apart from how the situation is making you feel are the effects it may be having on your children.
