Friend's EX Boyfriend

Is it okay?

Can I really have feelings for you? Is this really okay? 

Yes, you are my friend's ex and I can never change that. You two shared something special. Even after she moved away, we still talk occasionally, but I still care a lot for her, she's still my friend .  I honestly feel like a bad friend. After you two broke up she started seeing one of my good guy friends, and she ended up falling in love with him.  Although it didn't work out between them, she still loves him to this day. Idk if this fact changes anything, but I still feel guilty.  If she ever finds out, she will be hurt, I know. Deep down it does kill me to do this to her, but I can't stop my feelings for you. I'm willing to face the consequences, I just hope you're worth it.
