Is it normal to feel this way about a current/former boyfriend's looks?

So I talked to my ex fiance (we were together for 2 years) for the first time in quite a long time last night, he called me unexpectedly. We had a nice, calm talk, and he wanted me to get on ooVoo with him. I had not seen him in ages. I used to think he was the best looking guy in the universe, I called him "the epitome of sex appeal" and other such terms. I saw him and did not find him even remotely attractive. He did not change too much since last time I saw him, besides cutting his long hair to medium length, (which I had kind of wanted him to do way back when) and losing a bit of weight. I just looked at his face, I did not find his eyes, facial structure, anything about him remotely attractive. It was almost like looking at somebody I had never seen before!

With my current boyfriend, I knew him for a LONG time before dating. I never found him attractive up until about 3 months before we got together. He did lose a lot of weight - 50 pounds, since when I first started talking to him to when I started dating him, but even when he was thinner maybe 5 months before we started dating, he asked me for a rate on his looks, and I gave him... a 6 I think. Now, I find him to be just stunning, I find him to be the hottest guy alive, I just look at photos of him or go on ooVoo, and of course in person, I feel that he is just SO good looking. But I did not feel that he was that amazing looking up until a few months before I started dating him...

is it normal for my feelings on boyfriends/ex boyfriends looks to change like this, even when their appearance barely changes?
