The boy's too big

Why has you boyfriend suddenly put on a lot of weight? Have you tried talking to him about his eating? Does he exercise? Does he know that you are turned off by his body size? If you love him, you will want to get to the bottom of this before searching around for an Adonis. (It could be a long search - there aren't that many of them in real life.) People often overeat because they're miserable about something else, so see if you can find out what the problem is. Be very very tactful, though, this is an incredibly sensitive area.
