Guys, Why would a man hide and keep old love letters from an ex?

Anonymous
A person they haven’t been with for 3 years. They have a kid together but she won’t allow him to see their kid or her.

He is now in another relationship with someone else (like say a year) and they’ve discussed marriage and stuff. Should he still have those letters?
