Forgiveness

How do you go about forgiving someone for their actions against you while they are still hurting you? I want to stop feeling angry and hurt. I wish I can permanently disconnect myself from this person but it's impossible because we share a young child. Even after he reaches the legal age of 18, we still will have to work as a parenting team. I need to make my own decisions in life and you should support me, afterall it's for our child's benefit. Isn't that the reality of splitting up and moving on? It seems he can't accpet that...let's be apart but live close enough. Since our child has been born we had a long-distance relationship because your schooling was the most important thing you needed to accomplish, fatherhood was secondary. I stuck it out and raised our son . Now that you are so close to the finish-line you figure that now you are ready, but my plans, location, etc must be convenient for you? I know that the frustration of the whole situation is fueling the fire between us, but I need to be at peace..if anything, for our beautiful boy.
