You can love people more when you trust yourself to be able to walk away.
People get so scared of “falling in love” or having intense feelings, romantic or not, for anyone. And I get that, you can get your heart stomped on. But being really into someone, romantically or platonically, is really good for you! It makes your day better when you think about them, it fills you with happy hormones, it just makes life more worth living.
When you get a bit old, and after you’ve already had your heart stomped on a few times, you can get pretty good at knowing when and how to walk away. And once you trust yourself to be able to walk away, then you can really dive into appreciating someone.
Go on and be obsessed. If they become an asshole you can say goodbye. And there is no need to feel bad about it. You gave love because you are a loving person, and they were the ones that lost that.
