What does boyA want to say, please?
The context is, boyA was hurt by a girl(maybe called Carla) before, so he didn't wanna make any relationship with any girl. Even didn't wanna let a girl live in his apartment.
But today, a girl rented his apartment, he wanted to send her away! But boyB didn't think so, so they had a chat.
----------
boyB:
Aber was es auch ist, wir können sie doch jetzt nicht einfach wieder wegschicken.
boyA:
Carla hätt' ich besser sofort wieder weggeschickt. Das wär' für alle besser gewesen.
----------
My question is, what does boyA exactly mean? Could you help me translate it into English? Thanks!
