For about 6 months I've been dating someone and if it's already going south I'd rather leave now than continue having doubts and questioning mine/his behaviour.
He'll occasionally call me by his ex girlfriend's name and I really cannot stand this. It just screams that he still somewhere in his mind has her in his thoughts. Fine if he does but I don't want to be the rebound or the buffer whilst he sorts himself out.
It's not even a similar name like Nicola vs Nicole. If he can't call me by my actual name then what hope is there?
I think I've already made up my mind but I don't know if IABU because it's just a name. But it's my name. Everyone else in my life with whom I don't even share any sort of intimacy with can remember to call me by my right name yet my own partner can't 
Sorry, rambling now and don't really know what my question is but would this be a deal breaker for you?
