You made the right choice in walking away.
Sometimes when we meet someone we thing 'they are perfect, if only they didn't do, x and think y.'
Unfortunately the things we don't like about them ARE them! We can't remove that part of them and have just the bits we like. We get a choice. Either like them all, include the way they do x and think y. Or choose something else.
Choosing something else over someone who is controlling and violent is the best choice (however much it hurts at the time).
That's not to say people can't change, but they don't generally change within a relationship! I mean if she couldn't keep a lid on it for 2 months, then it is only going to get worse.
Get some good friends around you, go out, have fun and re-discover some good things in life. If it still hurts after a while and feels like it is dragging on have a look at EFT (
EFT Home - World Center for EFT (Emotional Freedom Techniques)) which is very helpful. However filling the gap with fun is usually the very best therapy and it's very enjoyable too.
