Weight gain/strength gains

I have for well over a year now maintained my weight in the 132 to 135 range. I follow a very basic weight lifting schedule where I deadlift bench press and overhead press. I recently added squatting which I had never done with very much weight before. I had finally built my strength to the point where I could do a decent squat around 135. I always felt like my form was too bad 2 really Squat and he serious weight so I kept to kettlebells and stuff like that. So I started squatting and then I gained a lot of weight on my bench and my overhead press. But now in the past month since I've added the squats I have gained on average 3 pounds a week every single week. My thighs have gone from twenty one and a half inch to 23 and 1/2 in. My waist from 26 to 28. My hips from 37 to 39. And so on. I have not changed my diet! There's no way I suddenly added 10000 calories a week to my diet. My boyfriend says this is a product of my training and I just have to deal with it if I want to lift heavy and make gains. And I really do I'm very happy that I got to the point where I can do 3 sets of 5 at 115 on the bench press. But it's kind of meaningless if I put on 12 pounds at that time too. Does anyone have any advice?
