Hi. My boyfriend called me by his ex'sname. In our first week of being in a relationship. He left her nearly 8 months ago. It that normal?

Sometimes that slip-up happens. It might be because something you said or did reminded him of Ex. You said or responded in some way... Two women did the same behavior with the same guy... for that Ex call to happen.- Think about that !!
He slipped up. It should be only a one-time thing. That sometimes happens.
How long were he and his ex together? If they were together for a while, I say he has not completely moved on from her or their relationship. So definitely not a good sign

Completely normal. That doesn't mean he wants to be back with her. How long were they together? It takes time to completely erase old associations.
That is not a good sign.
I guess it could be possible
It happens, but means nothing. Relax.
No it's not normal
