Question!

So if you've been dating someone for almost two years and have a kid together but your fiancé previously had a baby before you two got together but he haven't seen that child in 3 years then all of a sudden she try to reach out to him and tell him he can have visitation for one hour a week but she has to be there, how would you feel about the whole thing? Also she never been in the picture since we've been dating and they never ever had communication for 3 years.
