I've been dating a fun, loyal unicorn for about a year now. I'm not on the verge of cutting things off with her, but since she graduated college and hasn't found a job, she's been stressed out and she's gaining some weight. Obviously I want her to be as attractive as possible, but it's a delicate situation because I don't feel that I can ask her straight up to lose the weight (society blah blah).

What do you guys do in situations like this?
