Thank you Chantos
I am 19 years old...
It's really difficult for me as this is my first major break up... I know I shouldn't feel guilty for going to the gym with a girl, and posting a picture of a friend in her underwear (I do photography), but my ex makes me feel so guilty...
She texted me and told me how bad of a person I was for posting that picture up, and intentionally hurting her... But I've always wanted to post that photo and although I knew that it would hurt her, I thought it was okay cause she knew breaking up with me would hurt me but still did it.
I know I shouldn't feel bad because she broke my heart and decided to leave me, but I feel like she's making a really big mistake and she's going to eventually come back to me.
I told her "I'd be waiting" and feel really pathetic for saying that... But I never wanted this break up, and still love her.
I'm doing the best I can to move on by seeing other girls, going to the gym, working hard but I feel afraid to leave her behind and just forget about everything...

I'm beginning to think that romance is just fiction.
Many would say to just go sleep with someone else... but I can't, because it doesn't feel right...
Please...
Someone help me...
