Basically, the way I see it, merely going out for a coffee and it being basically the same as with any friend or any other person, it would not necessarily require full disclosure at an early stage. Basically, whoever you invite to a coffee or dance or some such is no one’s business until one has a claim of sorts (and I don’t mean a claim to you as in marriage, I mean any sort of real claim to knowing about such things). In my view, kissing someone or giving him/her a love letter or an explicitly romantic gift or taking that person to an explicitly romantic place or declaring strong feelings, would create such a claim (and basing on the circumstances, “lesser” things also could create such a claim). Plus, the concern which Whatevergirl has raised before, i.e. that a heart can’t be divided. Personally, I’m against this form of polyamory which is multiple romance. However, I am reacting emotionally to it, which means my reasoning may also be emotional. However, I don’t see a rational justification making it good, either (expedient at best, but that’s not enough). At the same time, I would be prepared to defend with similar zeal the idea that merely asking someone out to a coffee or even a dance or merely communicating some interest (in a person, not in a relationship) doesn’t make a “claim” yet, but it takes one of the heavier weight things.
