Am I crazy?

Okay so like this might sound bad but try and put yourself in my position, my boyfriend hooked up with another girl that has the same name as me. I personally, am almost finding this a deal breaker. I understand he can’t change it or anything but it just makes me so uncomfortable, I wouldn’t feel like one day he could propose to me and say my name and it be genuine, and every time I hear him say my name I get uncomfortable. I wanted to maybe name my daughter after me cause I was named after my mother and I don’t feel comfortable doing that if he’s slept with someone with that name.

EDIT: I feel like he thinks of another girl every time he says my name now
