Is this abusive behavior?

Whenever me and my boyfriend are out in public and I look at another guy (not necessarily because I want to or I’m checking him out) but because I have freakin eyes and if a guy is in my eyesight I just may happen to see him. So what? Right? Every time we come home my boyfriend picks a fight we me saying how he saw me looking at guys, and that he doesn’t approve of it. I have no intentions to cheat (especially while out WITH my boyfriend). I really only have eyes for him but this sort of issue pushes me away. I can’t come in contact with any man for whatever reason without him blowing it out of proportion! Eh, idk what do you guys think?
