Don't feel stupid for missing him, even if he treated you like shit.you still had happy memories. & You’re A L W A Y S going to miss them.
Don’t try to replace him, cause you won't. Just get through each day
& eventually it'll get better. I promise. Eventually someone will come
into your life, & whether or not you realize it, they're going to be
something special to you. So don't throw yourself at every guy you see,
trying to replace him, or at least dull the memories. Cause you're only
going to make yourself see how hard he is to replace. Someone better
will eventually come along
