You shouldn't be put off by his name. He cant help it , his parents gave it to him, he's stuck with it now. You should consider that you are being very doubtful of him. His name shouldn't matter you could give him a nickname that you both like haha
If I met a girl with an awful name I'd be worried about wtf type of parents she has and if it had any effect on her upbringing. But if it's actually just a regular name that you don't like I don't really see the big deal
One time the guy I was getting to know had the same name as my brother, I tried to ignore it but in the end I just couldnt stop thinking about if the relationship went any further...*shudder*
