My son's father left me before the birth of our son. After some time of not communicating. We have spoken again and come to an agreement due to our son. But after I thought my feelings for him were non existent anymore we've been broken up for 12 months already!! And just seeing him again recently. Have triggered my emotions. I know there is no hope for us. Since he has moved on and has been with a female for a while. But it seems I haven't. How can I control my emotions if I can't let go?
