So I have lived with my boyfriend of two years for about 6 months now, and things have lately taken a turn for the worse. We've been trying to compromise on spending time with each of our families and reserving special time for each other but one thing has really not been resolved yet. I am 5'6" and 135 pounds and basically in average shape, but when I had first moved in with him, I was at least 15 pounds skinnier and was a gym-aholic. Due to getting a promotion at work and changing my daily routine, I gained some weight and stopped going to the gym. Lately, he's been saying things like "you're not that fat" and "maybe you should go back to the gym" but tonight, things really got ugly. I was trying to be playful when we got back to dinner and put him in the mood, and his reply (with a grin on his face) was this- "We can have sex when you go to the gym." I freaked out and spent another night in our spare bedroom, which would be the second night in a row.
