Don’t feel stupid for missing him, even if he treated you like shit.
You still had happy memories, & you’re always going to miss them.
Don’t try to replace him because 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 the dull memories because you’re only
going to make yourself see how hard he is to replace. Someone
better will eventually come along.
