Right in all the wrong ways

I don't seem to mold into your body the same way as him and I once did. I know your kisses are different.
You stroke my hair from different angles. Your scent of morning breath is unfamiliar.
You sleep in tank tops, we slept together in t-shirts.
You call me 'hun', he called me 'baby'. His music taste was awful, yours and mine are just the same.
Your social skills and friends are different. I like your arms. A lot.
You are kinder than he was, you are much more suited for loving. But I will do bad by you, as he did bad by me.
I ought to love you, I know I'll try. But when it all comes down to it, you're not him. And when we're laying there at night, my head upon your chest, it's not your heartbeat I'm hearing, but one from another life.
You are not like him. I loved him first.
