Cheating?

Yes.

In that case, yes; it would make me uncomfortable and make me wonder why he's doing that, what's he's trying to get from them that he couldn't from me. That might not be cheating in and of itself, but it feels like it's the gateway to it to me...

Well him liking them could just be him being male, being attracted to what he sees. Let him know how you feel about it. I'd be more concerned about the tone of the conversations, because if that's just friendly it's alright, but if it's flirty that's a big issue

@MrMagic: but how are u supposed to know..people are very sneaky

@WanderLustChick: If you tell him you're uncomfortable with him doing something, and he keeps doing it, then he clearly doesn't care about your feelings or [i]you[/i]. If he's flirting with another woman you should probably toss him aside. If he's unwilling to show you the conversations, he probably has things to hide. It's not that complicated

yep that would be uncomfortable.

@MrMagic: your right
