How can I emotionally detach myself a bit?

[Tyler]

Don't detach yourself from your emotions. Emotions make up you character, which is what makes you different from everyone else. Don't try anything stupid and try to make your move on her while she has a boyfriend. It will complicate things more. Wait it out, because if he cheated on her once, it WILL happen again. Afterwards, tell her how you feel. Spill everything. About her dating her ex again. About how you cried. Everything. I know that it's not as easy as it seems but it's your only way. I know because I made the mistake of hiding my emotions. The first time I truly felt love towards someone, I let it waste away. I've never felt the same towards anyone else. Don't make the same mistake I did. Anyways, if she turns you down, sorry, but that means that she never had feelings for you from the start. Good luck and take care!
