Hi so this will be cross posted because I need as much help as I can get. Please read everything before responding and if you need clarification just ask!

So I'm very new to polyamory and recently discovered I'm polyamorous myself. I entered a queer platonic relationship with my temporary roommate and best friend of 3 years. Over the course of these months I've fallen in love with her and while she loves me back she doesn't experience love in the same way because she's aromantic. She also has a partner/future spouse (another longstanding friend that that she's known for years as well but longer than me) and they got together a little bit before we did. Now I mention her being aromantic because she doesn't love me romantically but still loves me just as much as the partner she does love romantically (there's some greek analogy for ace folks who experience this and I can't remember how to explain it).

Either way there are boundaries established and (I guess what feels like) different committment levels? Some boundaries because it's like 99% likely my metamour is monogamous is that I currently can't do much of anything with my partner outside of cheek kissing and cuddling etc. Physical intimacy is my primary love language and I've learned over time that I do find sex and other forms of physical intimacy equally very important.

The other bit is one day my partner and I will be nesting partners but because of current circumstances we can't right now. She is however moving to be with my metamour which is good. I'm happy for her and my metamour but I have all sorts of negitive feelings because they get to do these things I wish I could with my partner.

They'll be nesting together, they'll have kids together and I'll be back in another state physically alone and what feels like is emotionally alone. It feels fucking awful.

We've talked about it, she reassures me and we set up boundaries but I'm still very unhappy with the situation. We're open but I struggle with dates and honestly feel it's a bit pointless while I'm here to try and date since I'll be moving back to my home state very very soon.

Logically I know things are fine and that she loves me but I still feel like shit. I feel jealous and envious of my metamour and like I'm less important.

Any tips on how to get your intrusive thoughts/insecurities handled? Any tips on coping with what feels like irrational jealousy and envy?
