Too many women jump into bed because we're so "in love" and we don't think about how we'll feel after. We get way too physical before we're even comfortable.
Thinking your partner is the same as you
Ladies, guys do not have the same thought process as you. Not even close. One mistake a lot of us make in our first serious relationship is thinking they feel and think the same way we do. And so when they don't react to something in the way you think they ought to, you get frustrated and upset.
This leads to arguments that your partner will, quite frankly, not get and therefore be unable to fix. Sometimes you literally have to spell out how you're feeling to a guy if you truly want him to understand where you're coming from. Early on, things being lost in translation convinces many of us that our partner just doesn't care.
Not accepting someone as they are
Why are people so hung up on fixing each other?
I have a novel idea: Find someone who is good enough right now. Too many people fall for partners who are broken in some way, and become obsessed with making them whole again. We put ourselves into a romantic movie of our own and then get pissed when the ending isn't what we expected.
