Just venting

So my girlfriend is demanding that I don't get over 200 pounds, I'm currently at 190 I'm 6 feet tall and 18 years old. I lift 5 days a week( sometimes 2 to 3 times a day) and I have pretty good toned muscles I'd guess probably 10 to 15% body fat, but there's no way I can stay under 200 pounds my muscles are getting bigger and I will pass 200 eventually I eat moderately healthy no soda or high sugar stuff.

(Pictures are after lunch so filled up with water, I drink more than 8 cups a day)
