How can you learn to give osmeone space and respect them if you never had to before... how can I stop being a ?

Well, that's the reason that someone would need space from someone else, is because they've never had it. Are you suffocating someone? It's an easy mistake to make. You enjoy being with someone so you want to be with that person every chance you get. DUH! But the easiest way to give that person their space is for YOU to focus on the things (other than that person) that are most important to you. Give a little extra time and energy at work/school. Hang out with friends more. Put in more time on hobbies. Pick up a new hobby. Visit with family. There are tons of ways to give someone else space, but the key thing is to stay busy so that you aren't worrying yourself, and so that you aren't pestering that person with calls, texts, emails and such.
