Throwaway because I'm unsure if my partner uses reddit, though I am certain she'd connect the dots, I just really don't want to hurt her feelings if she ever uses my phone or peruses my main profile.
I started dating my partner a little over a year ago, She is poly, her girlfriend and I are not. She has been with her girlfriend for 7ish years, they live together, and are (supposedly) non-hierarchical. They are also in the states, I'm Canadian (we met online) so we don't get to see each other in person often.
Over the months, she has started spending less and less time with me in calls, we don't do the activities that we fell in love doing anymore, and it seems like the only time she seeks my attention now is when her girlfriend is away on a trip or otherwise occupied. She once wanted to send me groceries and sent something that her girlfriend likes and I'm not particularly fond of, which is fine but then the things started to pile up... If we're going to watch a movie it's always one of her girlfriends favourites. If she gives me a compliment, she immediately retracts it and rewords it so her girlfriend is included (ex. *"*I have such a beautiful partner. No, I have two beautiful partners!" when her girlfriend isn't even there). She talks about how much I'll love taking trips to her girlfriends family home. If I try to tell her about a new thing I'm into, she relates it to her girlfriend and tells me I should talk to her about it. She jokes about how confusing it'll be when we all live together because she calls us the same pet names. She told me that she never wanted to get married, but "feels different with me," and eventually told me that she and her girlfriend have discussed marriage but it's just not something that her girlfriend is into (killing any desire or excitement I had to maybe propose someday). When the topic of visiting the states came up, she expected me to sleep in her and her girlfriends bed, her girlfriend would take the couch. I told her I am absolutely not comfortable with that and would rather book a motel room. Her response is that she hopes someday I feel compersion.
I don't think she's doing it intentionally or with malice, and I've tried gently broaching the concept of keeping our relationships a little more separate, but every chance she gets she relates things to her girlfriend. It really doesn't feel non-hierarchical, she started exploring polyamory at some point into their relationship, and I feel like I'm just there for her to explore avenues that she otherwise couldn't. She has made it clear that she never wants to move to Canada (understandable), and wants me to move to the states, but I really don't want to move countries just to feel like an on-call girlfriend (especially considering I would be giving up quite a few conveniences that aren't available in the states). It really hurts because I do love her so so much, she is an amazing person, but I feel like she's unintentionally seeking a copy of or more time with her long-term girlfriend, who I couldn't be more different than if I tried.
So ya, just wanted to vent in case anyone has experienced this and can give me some guidance or advice on how to further approach it. We're in our 30s and lesbians since it wasn't clear above. Thanks for reading <3
