Ugh you sound like my boyfriend.
I don't agree, if the person you are with respects you for real then they would never use your short comings against you. Not even in an argument.
Everyone needs someone they can open up too holding all that angst in is bad for your psyche. Im slowly but surly helping my guy open up to me. Just cause you don't tell us doesn't mean we dont know. Sometimes i feel so helpless when he's upset and wont tell me whats wrong because I sincerely want to help him feel better. Relationships should be give and take on both end. I can't be the only one satisfied emotionally, i wouldnt be comfortable. In the back of my mind id always think there was someone else he is open with and im not able to satisfy that for him. I need that connection. There are times that i get so frustrated with him lol. I understand tho, its harder for some people to let those reservations go. Especially if they've been hurt in the past.
But i def agree with what
@infinityaxis
has said. But there are other tangibles that makes a man a man and also separates them from each other. I like to think that no two men are a like. Its why for the most part i try to judge on a case by case basis, even tho ive been known to throw out the all men are dogs moniker around from time to time.
