Hope for the best with your Aunt. Have lost a few (younger than me) family members to the big C.

As for your GF...... well...... probably better off knowing now instead of later. Remember...... women out number men 2:1 in this world, so the next (and hopefuly better) girl could be right around the corner. Just don't get in the mindset of "My last GF cheated on me, so this next one is going to also". It will ruin that future relationship.

Chin up.

Don't worry about it too much bro, I know it hurts now but time will help. In the long run shes done you a favour, you really wouldn't want to spend the rest of your life with someone like that would you?

Best of luck to your aunt.

Erf...this is an hard step in your life, but stay strong! Good luck to your aunt

If she did it once, she'll do it again. Like Docwarren said ur better off. You're young and you live in Europe....what you need now is a road trip! Live it up man! Go wild!

The same happened to me man. I can completely understand how shitty u feel at the moment but nevertheless time will help you to get over it. It takes a long time but i could do it and so can you! Stay strong mate

i know the feeling of that. my dad had cancer. Sadly he died. Try to feel better going out with your friends and i woulnt reccomend you to feel bad for your gf. if he cheated on you, she didnt love you at all. you may find a person better that makes you happier.
