"I wanna love, I wanna leave,
I want you to love me, I want you to leave me."
It sounds like he wants the relationship to work, but he knows it'll be better for both of them if it ends. He's begging one of them to leave, though he still wants to love her and be loved.
"I wish I could be somebody else
Wish I could see you in myself
Wish there was something inside me
To keep you beside me"
He wishes that there was more of a connection or that they had more in common, to "see her in himself". And he wants her to, if she's going to love him, love him for the person he is, not whatever front he may have put up.
"I should have told you everything"
He wants to go back and prevent whatever misconceptions led to this point in the relationship, or lack of one.
