Kudos to your husband! Give him a high 5 for me. I would expect my husband to disentangle himself from someone cruising for a woman, too. And once your husband walked away the guy had to know that your husband would 1. tell you, and 2. you would tell your girlfriend--especially because she was home with you. You had no choice AND I doubt if he will ever put either of you in that position, again. Did your girlfriend think she and military boy were exclusive? If she cops an attitude with you when you have the talk ask her to explain to you what she thinks you "should" have done.
