My Bittersweet Frenemy

My bittersweet frenemy is not my friend or enemy; he's neither all bitter and at times he's sweet. He's a bit of both and that's unique. Around him I can be myself; but why just him and no one else? That's just a thing I do not know but I can't help but let my feelings show. He makes me giggle, he makes me laugh, he knows what I've been through, he's been down that path. He can be a jerk at times, but he's in my lyrics, he's in my rhymes, he gave me a reason to stay alive. He's my inspiration, my best friend, my first love.
