how to speedrun breaking a relationship:
>have thought
>think about it on your own, try to solve your own problems yourself
>don't share with your partner, do it by yourself
>gradually get more distant, relationship feels fake, no longer happy to see each other, feels like a chore, try to avoid your partner whenever there's trouble, feels weird and forced to do things together
>sooner or later someone explodes and both get mad at each other and break up

how to actually make a relationship work:
>have thought
>ok I'm not proud of it, it doesn't make me cool, it's actually pretty lame, whatever, lets share what I'm thinking with my partner
>partner understands you better now, reassures you that you're fine the way you are, you feel more comfortable together than ever before
>partner tells you uncool cringe stuff about themselves, whatever, you knew you already liked them the way they are, tell them that uncool stuff is just part of who they are and kiss them, they become more comfortable with you and feel closer to you
>have hot steamy sex and dream about your partner at nights
