Hey kiddo, do you ever play with toys and then decide you don't want to play with them anymore? Well, sometimes grown-ups have relationships with other grown-ups and they decide they don't want to be in that relationship anymore.
This is called interpersonal communication relationship dissolution, which means that the way people talk to each other can end their relationship. It can happen in a lot of different ways, like if they don't agree on important things or if they don't listen to each other or if they don't have fun together.
When a relationship starts to dissolve, it can make both people feel sad or scared. They might argue more or try to avoid talking to each other. But it's important for them to talk honestly about their feelings and what they want. It's hard, but it's better than pretending everything is okay when it's not.
Sometimes people can work through their problems and stay in a relationship, and sometimes they decide it's time to say goodbye. It's okay to have different relationships in life, and sometimes it's better to let go of something that's not making you happy anymore.
