everybody who fell in love and got cheated on would definitely go through what you're going through. so yes, you're normal.. you won't be normal if you didn't react to anything so celebrate! you're normal! lol just kidding

but anyways, move on with your life. though i understand that you're deeply hurt and would want to make her feel how you feel, she obviously didn't give a damn about you. so no use getting revenge. plus, revenge is not good. whatever she did to you will eventually get back at her.. maybe not now but at one point of her life it will.

look at the bright side of life.

so gather your wits and celebrate! you got rid of her.. and you're normal!!!!!!!!!!!
