Got ex pregnant. Baby came out and now picking baby names to give him. I picked a name I liked, let's say 'Tim'. Ex never tells me about the relationships she's had/fucked before me. Her sex life is a mystery. Turns out she had an ex named 'Tim'. I'm not planning to spend my life with this chick, just pay what I got to pay for my son and visit him.

Should I change the name or say fuck it I like the name and keep it no matter what?

Edit: I'm sticking with 'Tim'. I chose it before and not going to cycle through names.
