Some people can put a brave face on to the world, and it doesn't mean that your partner's feeling any less anxious about the impending court case than you are. That's by the by. It sounds as though you can't accept that your ex's found someone else so quickly, and whilst it may hurt right now, you don't know how lucky you are to be rid of him. Eventually, when the time's right, you'll meet someone else, who'll hopefully treat you well. Once your self esteem comes back, you'll wonder why you were ever thinking like you do now. Best of luck.
