Ok, now I am beyond livid. We actually did a lot of talking today. I started feeling a bit better about him continuing to see her and see where thier budding relationship might go... he's been chatting with her a good part of the night, I even briefly chatted with her, and she is supposed to meet me this weekend, before they go out again. He mentioned they might have an overnight visit soon. I'm a little concerned, and tell him so.
He just took a shower and I asked him if I could read his chat log with her. He allowed me to read it.... she made a comment about "not usually sleeping with someone on a first meeting." I fucking went off. I am so mad.
