Am I wrong for doing this?

My bf drove down for vday and we had a really great time. We went to dinner and I noticed he was looking around a lot and I mean looking back and forth at a pretty waiter. Tbh I think it’s okay to find someone attractive. I just don’t find it okay to stare esp w your SO in front of you. Anyway.. I saw him looking around a lot and it kinda bothered me. At one point he seemed to get all weird and it bothered me. I asked him at one point what he was looking at and he was staring at someone else’s food. He has a habit of looking at people and getting ideas of what they’re wearing and suggests itd look good on me & so on. He has never ever given me a reason to doubt him. I just guess I am a bit influenced with what I read on Glow sometimes and suspect the worst when it’s not really true in my relationship. I had a bad habit of dating guys who were assholes and my current bf treats me so well and I guess it’s a self sabotage kind of thing I’m doing. I called him out on it when we got in the car and he got upset at me - more like disappointed that I brought that up. He said no he was not - he just likes looking at other people and staying very alert as to who walks in (he really does & points out the crazies 😂). He said he would not try to be marrying me and is a very simple person who doesn’t get jealous. He said he’s not the type to get upset if I gush about a crazy good looking guy or look at a guys outfit and get ideas for him to wear. I guess I just read him completely wrong and I’m not used to having someone so good and honest. He does all the right things and I hate that I came off insecure with him and he called me out for it. I of course never accused him of doing something wrong and only questioned it calmly. Wish I can stop these self sabotaging habits. Would any of you have felt the same way if you were in my place?
