Never forget that you are in the business of emotions.
When you start showing that you you struggle and feel uncomfortable when there is tension between you and her...
When you show anger, confusion, indecisiveness,
When you overshare and show signs that your emotions are controlling you.....
And when you tell yourself stories that "this one is different", and you justify getting too close to her....
...she will eventually lose interest, disconnect, and at best gives you attention only as an act of mercy. Not because she wants to, but because she feels sorry for you, looking down on you with silent condescension offering you pity love.
When this happens, in her mind, she has conquered you. Meanwhile, she starts to dream of a man who is emotionally grounded and doesn't lose himself through tough times.
Women follow strength. Take your negative emotions elsewhere.
Feeling emotions → healthy but being controlled by emotions → weakness.
Take them to me or a therapist. Take them to your brother or close male friends...
Those emotions are not welcome in romantic relationships.
I know I am being hard on you but you need to hear this over and over.
She is there to have a good time with you. She is not there to fix your problems; if anything she usually adds to them.
And don't fall for her instructions if she encourages you to open up. She doesn't know how to be a man yet alone giving you tips on how to act as a man. At best she will unintentionally instruct you how to be a woman which will end up making her resent you.
Never forget these 3 letters:
F-Y-B... meaning "Find Your Balls".
Stay strong, recognize that your issues come down to not understanding emotions. Never let emotions get the best of you when there is tension. Keep your cool like James Bond.
If something bothers you, communicate properly and confidently. Yelling, screaming, aggression, and passive-aggression will not take you far.
And always remember that you are just another couple: a man and a woman. Many men lose their way by assuming they are different.
Go gethem.
