I haven't any real advice for you there, I'm sorry. [Not for the lack of advice, really, he's more sorry that Martin hasn't had anyone treat him the way he deserves to be treated.] But you're allowed to have emotions, yeah? It's alright if something hurts and you're mad about it, that's not unreasonable. You don't just have to take it. That's not what love is.
