Here's my 2 cents - ask her! I know it's a tough question but sometimes you have to put those feelings aside and be totally honest. I am just in a reunion with my bson and haven't asked him either but we are still meeting in public places and neither of us wants to involve the rest of the family yet as we're enjoying each other's company and trying to build a trusting relationship.
One of my fears is that we'll be out for dinner or a walk and run into friends or co-workers and then what? How to explain what me, as a 44 year old happily married woman is doing having dinner with a very good looking 26 year old! The tongues will be flapping! I too am looking forward to introducing him as "my son" but would never do so without speaking to him about it first. Since we're early on it might be too soon for me to approach the subject but if you're comfortable in your relationship, and it sounds like you are, then go for it!
