i know breakups can really be hard. here's some good advice i was given a few months ago when i had a breakup. it's good to cry, cry when you feel like it. let yourself be happy with who you are and know that there are good things out there just waiting for you! you will love again, and your heart will heal.
remember that we're here for you.
as for the tears not coming, sometimes they don't. i used to never cry - about anything. now sometimes it's like i can't stop. but like i said, if at times you feel like crying, just let it come out....and if tears don't come, don't worry. everyone takes pain differently. my heart goes out to you. *big hug*
