Hello folks, my name is Jennifer. I'm the proud mother of a teen son who is heading off to college in the fall. He was dating a lovely girl for the past six months. I think the world of her too, and she too will be leaving for college in a few months. I suggested to him that now might be a good time to have a discussion with his girlfriend about making sure things don't get too serious. They'll both be meeting many new people at college, and should be open dating to other folks. Otherwise, if the relationship gets too serious by the time they leave for college, either he or she could get seriously hurt upon learning of another love interest. Keep in mind, I'm not trying to meddle in his personal life, I just wanted to offer some advice, and it was solely his prerogative to act on it. He actually agreed with me and thought it was a good idea.
Well, unfortunately the conversation with his girlfriend did not go as smoothly as he would have liked

He came home shortly after having "the talk", pointed to his cheek, where upon looking closely I saw some faint red finger print marks, and said jokingly "Well Mom, do you have any more wonderful advice for me?" Apparently she got quite upset and slapped his face. He attributed it to a poor choice of words on his part. During the course of the conversation, he told her that he would probably meet many new "intelligent and attractive" women at college. Not implying in any way that she was neither attractive nor intelligent, though thats the way she interpreted it.
He took it in stride, but I do a feel rather badly that I put him in this position. All I could really tell him was that I never promised it would be easy, and she's apparently a very emotional girl who has strong feelings for him, but she's also very sensible, and eventually she'll come to realize that it was the right thing to do. Its not his fault that she reacted the way she did, he may have been perfectly diplomatic. Women are just emotional creatures. Then I gave him some ice for his cheek
Do you think I gave him the right advice and handled this the right way? Many thanks for your feedback.
Jennifer
