Why don't boyfriends comment on their girlfriends pictures on facebook?

[Razule]

Granted while most won't have consciously thought into it as much as I'm about to explain their subconscious most likely has. If a boy (boyfriend or not) comments on a girl's picture it can be taken the wrong way by her and those reading the comments. A compliment could be read wrong and be seen with much more value than they wanted. Simply saying "you look nice" can turn into "he likes her", "why only nice? why not great?", "he's just saying that and doesn't really mean it" ect. More or less commenting on pictures, haircuts and other "how do I look?" related items or even on things she's taken pictures of just come off as a giant minefield of what if's. Standard guy reaction is to not say anything. If you don't say anything you can't get in trouble, is the standard idea. IMO anyways.
