That's why you have to stand up for yourself, dont be afraid to talk about that. Dont be hesitant its important to remain your masculine frame that this manga pretty munch does not have prob bc for the entertainment romcom genre. Respect is key if she gets mad tell her why you are unsure if she would respect you she would understand your reasoning, if she gets mad "your being insecure" or some other blah blah retarted feminism bullshit that tries to weaponize against you. Set rules for yourself in a relationship. Just leave her ,as you said "not all woman are like that", but for people to respect you you need to first respect yourself. Are you fat,skinny ? Your own ego will tell you that your fine the way you are or are to lazy to change yourself. atleast myself i have built my aesthetic physique i fixed this myself. But idk this manga is pretty much an example what not to do which makes it pretty funny to read. oh yeah also its not what happend to woman these days you should blame yourself and the feminine men for the problems most relationships have. its good that you experience these kinds of thinks if learned correctly it will manifest you into the best version of yourself. and yes you should look at others at where you are standing,the world is a competition hate it or love it. Get on self improvement trust me king it will help you in the long run there is an entire community willing to help you. Goodluck king
