You did the right thing, jc. Hang in there, as vlad said everything will fall into places in no time. I know it's scary to be alone after being with someone for so long, I once broke up with someone of 7 years, I never knew what it meant when people said it hurt in your heart like it's being stabbed before that. The emptiness is excruciating. BUT you have to know that you are brave enough to break up with him, you will be tough enough to be on your own, you have done the toughest part now. Law school must be keeping you busy which is a great thing at this moment. Puppy love or long relationship or marriage, it's the same in terms of you'd hope that the 2 persons grow together, everyone changes, only we hope or try to change in the same direction. When you don't and start moving in different direction, it's a wise thing to let it go.
You are young and will finish your law school, you have a great life ahead of you, so look forward to that. DON'T start looking around to find someone to feel the emptiness, absolutely NOT. I made that mistake and I am still regreting it! You always find the wrong one on a rebound hunt. Take some time on your own, enjoy life, have fun with your friends. The right one will come without you even looking, corny but very true!

Big hug!
