Then don't waste your time. Tell him that once he leaves, he's free to spend his time with Rosie Palm and her five sisters, because it's over.

Tell that waste of space to get the fuck out of your house, go find a man who will treat you right!

Not worth your time, get rid of him, if he is so superficial...

PLEASE don’t stay with him. He’s not gonna change, he’s just an ass. Cut your losses and move on - you deserve so much better.

This really depends how much weight we are talking about. Also, why the hell aren't you two video-chatting, sending pics, etc. Get snspchat.

Wow....
So, if you put on enough weight to really make a difference in your appearance, in a short amount of time? He should have been concerned you had a medical issue such as depression, hypothyroidism, etc. that triggered it.
If it wasn't a lot of weight and he's upset by a few extra pounds? Well, definitely not a "f*ck him" time ;)
Just remember that he spent a lot of cash to be miserable and go hang out with your friends and enjoy yourself! If he's not happy he can trade his tickets for an earlier leave time. As it is? He should be damn grateful you didn't kick him straight out to a hotel.

Time to shed some dead weight! The partner, of course.

That's some highly abusive bullshit. He can leave.

This isn't an issue, he can just picture your roommate.
