VG, part of how they rationalise their actions is they rewrite the relationship history, this makes it easier for them to justify their behaviour. Please dont take this too much to heart. Everyone has a different tolerance level for certain kinds of behaviour - in my view he has made a point of telling you he is with someone else. He has done this for a reason, so that he can blame his behaviour on you, dont take it on board. He is wrong because he is ill and in your heart you know it, this doesnt excuse how he has behaved, even if it does explain it. Take this opportunity to concentrate on yourself and your daughter, spend lots of time together doing fun things and start to enjoy your life again,
hugs,
