Stealing Ex’s baby name

My ex and I always talked about having kids and even had names picked out.

I am now pregnant with my current bf and want to use one of the names my ex picked out.

Is this weird? I really love the name but sort of find it odd and off putting considering how things ended between us. Not to mention how my partner would feel if he knew that it was my ex who put the name in my head.

I’m sure I wouldn’t appreciate him wanting to name our child something his ex had picked out.

What are your opinions? I wouldn’t actually use the name as we have names picked out already, but am I horrible for wanting to do this?
