Ringoo,
Consider that a hurricane loses its strength as it blows and blows. Said differently, yes, it does sound like she is dumping on you, and is that OK? What is happening on her side that is leading her pick fights? Stress overload? Overwhelmed by something?
Sometimes “friends” just dump, overlooking the other, and there is no obligation to help them find happiness. If you can help, though, have the space to bring comfort… such as listening and validating her stories, hug her, and invite her to something lighter, it could go a long way for you both! 🙂 For example “wow, yeah, that sounds painful (hugs). Friend, even though your day was long, the night is young and the stars are out. How about we go check out that art museum?” Nod, smile, listen, and bring the cheer. If you don’t grab onto her stories (such as to fix her or judge her) then perhaps her winds won’t press as hard against your own shoulders.
With warmth,
Matt
