When I say "complimenting" I mean simple things like saying that a guy has a nice haircut or the dress a girl is wearing is pretty. Really, non lewd/flirty compliments. I've been in relationships where I could openly comment and discuss a stranger's attractiveness with a partner. However, in my most recent relationship, I've often gotten in trouble for complimenting another girl (female friends included) on the simplest thing. I don't compliment strangers and friends the same way I compliment my girlfriend but she still gets upset at me for doing it (more so with strangers). Am I in the wrong? Is she a little too jealous? Am I wrong for just trying to be nice?
