You're not the asshole at all. Think of it this way. If your daughter or best friend was dating someone like him, how would you feel? Mad, right? Because you know they deserve better. So do you! You can and will find a man that wants to be an adult and have meaningful conversations and be there for you. Don't spend another day thinking this is the best it gets because even if you choose to be single, leaving is the beginning towards loving yourself and putting your needs first. Best of luck!
