New boyfriend said to my friend ‘it’s going very well for now’ what does that mean?

New relationship, seems to be going well at the moment not too much pressure but I’m a little nervous. Guy I’m seeing says he has a female friend in another state who he wants to see a few times a year and is very close to. He says he had feelings for her many years ago and whatever happens between us that will never change.. should I be concerned?
