Most Helpful Guy
They're not. Guys are very clear cut, what they say they mean what they mean they say almost 99% of the time unless they're players.
That's the thing about guys, they're literal in every sense. If a guy says how was your day, he's literally asking how as was your day. If he's complaining about something at work, he's literally complaining about something at work.
With women, you asking how our day is going is rarely about just figuring out how our day is going, or if you complain about something at work it's not about that subject, there's almost always a different content to the message. Classic examples:
"I'm fine" and then the passive aggressive chain of actions and comments begin.
"We can do whatever you want to do..." and so begins the guilt trip, and later a "debt" that has to be repaid.

Girls and guys both make up so many excuses to think someone likes us even when the writing is on the wall that they don't. If someone says they like you BUT... listen to what they say after BUT because chances are, the first part was just being polite. If they haven't made a move despite many chances to do so, it doesn't matter if they "stare " or whatever else can be pulled out if the air, it's time to move on. If they never text first, take forever to respond or don't respond at all or only answer briefly to be polite, move on. If they used to text but don't anymore, move on... because they already have. If they seem like they only want sex, chances are that's all they want.
The dating world would be so much easier if people accepted things at face value instead of trying to reason away rejection. The only time girls and guys are hard to understand is when we try to interpret hidden meanings where there aren't any.
