I think you’ve done the right thing contacting him. It sounds like it went well.
It’s early there’s no need to consider re-establishing any R other than one of friends and co-parents at this point.

You also need to consider you current partner. Was he a rebound? What sort of life have you built with him? Should you be honest with him and let him know that your X has been in touch – that only seems fair.
