I am so sorry you had to do this. Break-ups are never easy, once you have your mind set, or things that need to be said...You have to get them off your chest. If thing's were and are workable, you can talk to get thing's the way the both of you are mutually happy. 3 years is a lot of time to put into a guy and a relationship...Best of Luck to...My thought's are with you.
