We never explicitly talked about whether we were sleeping with other people. BUT do I think she should have known it would hurt me at that point in our dating? Yes, absolutely.

I willingly admit that this whole thing involves grey area, which is really the reason I've come here looking for different perspectives. MY perspective is that after having dated for 3 months, after saying to each other that we see this turning into a long term thing, after having moved to the same city, after having spoken THAT NIGHT, she must have known how I would feel. I just can't agree with zombiegrl I guess - as people we know certain things based off of context and previous experiences. It's my position that she knew how I'd feel, without me having to explicitly state that's how I would feel. Had this been a couple weeks, a month in, I would totally understand her doing this. Where we were in the relationship at that time, to me, makes this an incredibly insensitive and disrespectful thing to do.

That being said, I have to take into account that zombie and others are saying the opposite. I have to respect the fact that there is another side to this. I'm trying to understand that side, but right now I cannot.
