So here's the thing I'm monogamous and my gf is poly with a long term nesting partner. So far it's been a smooth 1year ride between myself and gf because we have our boundaries respected and we communicate really well together. Recently my gf and her partner have decided to upgrade to a bigger home.

Not gonna lie it made me feel jealous and I started having these questions in my head, will I also get to achieve such relationship milestones with her? If not getting a home with her is not possible then what kind of markers are there to show my significance? I feel eventually the best outcome is her, my meta and myself form a V. However from past conversations I don't think my meta is ready to accept me and I have yet to meet her too because I'm in another country.

This is also my first relationship with someone who is actually a polyamorist. The negative feelings I harbour are not towards my gf or my meta. It's more like I am concern as I do not know how to navigate my emotions without the set rules of a typical relationship escalator. Like I can't just go out on a limb and live on the emotion of love without some sort of milestone event as evidence that we share a life. Any advice on this is most welcomed! Also for context we're all lesbians here.
