I am no expert at all this but I would just say... be happy for the time you had with him. Maybe it will be better in the long run that the 2 of you are not together. If he slept with some other woman, then maybe its better knowing that you arent together. Love yourself and move on. If he doesnt love you... no sense wasting your heart on someone thats not there to love in the first place. We love you here! Big hugs!
