Thank you for replying so quickly.
You are spot on with her best friend. We have been talking with her for the past 2 months and she says to remain supportive of our daughter but don't push. Her parents pushed and she ended up staying in the relationship longer than she would have (to prove them wrong).
Sounds like we should put on our "game face" and go along with everything (the move, accept him as part of the family, etc)???
Her friends are throwing her a graduation party tonight (just the girlfriends), their intention is to bring some things up tonight. She we tell them not to since we want her to be able to talk to her friends so that we can keep an eye on things (escalation)?
