Hello? Industry reports does not mean he is sleeping with her. Where is the proof necessary to lay down a gauntlet?
I could very well be insane here, but what changed between the two of you BEFORE he went to Europe?
I don't think he is sleeping with her. I think this is an unrequited sitution.
Things hadn't changed before he went to Europe. He had even wanted me to come earlier and stay longer than I had planned. He changed after the event where he saw her again. I have verified that she is no longer with her BF. Very odd that he has told me so much of what he is doing and with who, and yet never mentioned seeing her, let alone working with her.
