Hello everybody. I have a friend who I've known for maybe 3 years, I go to his house a lot and we play ps4 and xbox1 sometimes, but mostly we talk about girls. Anyways yesterday I was at his house and he was telling me how jealous he was of how I started dating a girl named Sue(Fake name). I went on to tell him "You know Brad(fake name), you could probably date girls as hot as the ones I date if you weren't so fat. I said it in a joking way but deep down I was hoping he got the message, to lose some weight. He's 5'9" and around 230lbs. He looked at me and said "wow, really dude?". Then he says he's tired and asks me to leave, so I go home and today I called him to hang out and he didn't pick up, and his mom said he left the house in the morning and hasn't come back. Maybe he went to get a gym membership LOL just kidding, but how can I make things right and also motivate him to lose weight?
