It's not the dates themselves, it's processing before and after. Because we're newly dating, and there are established outside but less frequent partners that they began dating slightly before me, we're simultaneously getting to know each other, and springing me into both polyamory and non- fidelity. Honestly, it is way too fast for me. But there are pre-established relationships and a preestablisjed pattern of openness.
On writing this out, I realized that the intense processing has nothing to do with the dates themselves, or not enough to be life-disturbing, but trying to deal with either miscommunications (I don 't live with them so they tend to communicate to each other and forget to include me, thorough they are working on this), or me figuring out when something felt bad, what, and why, and how to ask for something more communicated if I need it.
When my communication needs aren't met, which seems every outside date right now, or if not on the date, in a metamour/dating event close to it, I tend to feel I cannot do this. I feel I'm not poly enough to be able to handle the openness.
Lovely's comment made me wonder if it would be easier if I knew my metamours. One is long-distance, and one I met briefly in passing, but did not get a chance to properly talk to or know yet. The other two have hung out or skyped, and I think between the miscommunications and not being introduced to partners, which is mainly logistics, and dealing with being hidden relationally with their families and friends (again, logistics) I tend to feel not important, especially if many of these things happen in close succession. But also recognize the fallacy of this. And I know in my heart when these issues aren't going on, or even when they are, how important I am.
I think all that will change in time. So maybe I need to wait for- and encourage - change, before expecting comfort of myself.
To clarify, too, I have no problems with my partners dating within the triad, but that might go without saying. And I feel that my needs are being met, minus communication. It's just the communication needs and errors are centering around dating right now. Or, at least, that's where errors are most frequent and most magnified, because of my sensitivity around it. And that sensitivity, I think, is newness. I have a lot of experiencing and reframing to do.
