I definitely know the type. Extremely needy and acts performative for extra attention. They'll dominate the conversation with positivity, lie and make up stories, one-up you in experiences, try to coat their insecurity with excessive charm — and the insecurity runs deep. One guy I knew stalked his ex for 2 years because he couldn't let go, another would show up at my house over and over unannounced. I had to frankly say to him "I'm sorry, but I can't be your friend". It was brutal but had to be done, otherwise you'll just resent them and spend all your time thinking of clever ways to avoid them. They don't see you for you, they see you as a means to fill a void in themselves.
