Man, that dude is sad. He really doesn't have your back. How can someone who loves you actually talk like that? Easy way out....You know what is the easy way out?
Having a friggin metabolism that allows you to stay thin while eating burgers, fries, pizza, candy, etc.
Never having to look at the scale and decide, I'm only going to have water instead of the friggin beer that everyone else will be drinking at the party.
As a matter of fact, the easy way out would be to say, "f** it! I don't care about my health. I don't care about my looks. I am just going to eat what I want, and drink what I want, and everyone can just Kiss My a**!"
Tell him that the next time he wants to be intimate, you already took the easy way out, and took care of yourself. Then tell him to do the same.
I'm a guy, and probably breaking man code, but damn!
