Cover art for Wake Up lyrics by Tim Armstrong

My take!

It's a song about somebody living with their ex-lover before they move apart. That's why he refers to her both as a "son of a bitch" and "my love of mine."

She comes and goes as she pleases, likely seeing new guys. This hurts him, because he still has feelings for her.

He isn't ready to move on, but he tries by dating a new girl. The problem is that his new girlfriend is just like his last one. And just like his first one. And all the ones in between. In other words, he is attracted to the wrong type of woman. He's trying to move on, but doing so in the wrong manner. He's trying to "keep moving away from sorrow," yet by dating the same type of woman he won't. He'll end up in the same situation that he is in now.
