Normally what I've done when dealing with break ups has been

1) Console in friends
2) Restrict contact with the other person

However, in my case the person I went out with dumped me regularly using different reasoning each time (Distance, other boys, depression etc.) and got me in a repeating cycle of getting together and getting hurt more. So cutting off contact in that case ended up being the best thing for me if for nothing more than to break that cycle after 2 years.

So really I'd suggest mostly just consoling with friends, or at least find something to distract your mind and let you enjoy yourself for a bit. 
You did well before the relationship, it's now mostly a process of getting back to that state again.

And I don't think you're villain or anything at all for what you did.
In fact I half-applaud you for having the strength to leave someone you love like that for their own well being.
I can relate to having to be in a relationship where finding time to be with one another is a hassle, and although it sucks when you can spend such little time together for some people it's enough to keep them going. There really is no right or wrong answer on what to do in such a case though, it's all up to the individuals in each situation.

It's a tough ride for everyone involved, I wish you both the best of luck whatever happens.
