I feel like I am in the minority because I don't think I know anyone who spends time buried in his/her phone like this. Hell, if I could get my friends to respond to my messages within a couple of days of me sending them, that would be a start!
Not at all. While still young, I learned to have realistic expectations about relationships. This saved me a lot of pain and heartache. So I've been lucky.
It actually sounds like you got disillusioned and probably heartbroken and are now scared of intimacy but don't realize it because you've activated a defense mechanism and are rationalizing your fear as "having realistic expectations".
Yes, and see how long that phase lasts. :)
