My boyfriend shows me he's interested in me by facing his body toward me and looking at me from time to time, but when we go up to another person in a store to ask for help for example, he always faces his body, feet chest and all toward them. I've noticed more often with prettier females, who often have a flirty vibe to them, aka check him out, give flirty eyes etc. Which isn't surprising, he's tall thin and has beautiful hair and face. And he doesn't really pay much attention to me at the moment unless I kinda tug at his attention. Of course it could be because I'm looking for it that I notice the females, because he pretty much just tells me how he doesn't like the way this old person was looking at him or that guy was just peeing in the bushes, he's really just a very observant person. Is it just him trying to be polite when he does this? Am I looking too far into this? Is he interested in other people once in a while?
