| | Is this crossing a boundary line?
Need some opinions on this situation: a man and woman who work together were flirting and had some sexually suggestive conversations together which both deemed as innocent until the man's girlfriend asked him to stop. He didn't realize his interactions at work bothered his girlfriend until she told him. He then stopped giving the co-worker attention and ended the suggestive talking to the girl at work. However, for his birthday, this same girl at his work got a cake for him; which he felt was "really thoughtful." The girlfriend is again upset. What could he/should he have done in this situation? I can't see him refusing the cake/Happy Birthday wishes since he didn't ask for it. How should the girlfriend now feel about this? He never actually discussed anything with the co-worker; just stopped interacting with her. Any advice out there?
