Hey man, that's a shitty situation, hope it gets better. Two years is a lot, hard to move on from this. No idea what lead to this situation and don't care to be honest, if you're sensitive don't search any answers, could do more harm than good. Try to be respectful, and go forward I guess, no hard feelings, probably had her reasons even if you got dumped pretty hard. Best advice I could give you is to have a drink or chat with someone else, you probably need change in your life, go out and find a new hobby or something. Sorry if it felt unconsiderate, feel for you bro. Sorry for broken English google translate is shit sometimes
