as someone who's struggling to make plans with my partner, i have realized that in a relationship, if your partner wanted to make time for you, they would do it.
It doesn't matter how busy someone is. If they want to see you, they will find a way.
like if everytime you reach out, they say something like "oh well i'm busy i don't have time" it gets to a point where it's no longer about them being busy (especially if they still hang out with other people!!)
that's my personal take on it
