So I have been with my boyfriend for almost two years. It was always poly and although it definitely does not come naturally to me I have put in a lot of work. We have both had casual partners during this time, this is probably where I am most comfortable. Lately I have met a person who I super click with but he does not have experience in poly and is new to it and we talked like let's just see where things go, but more than casual. Around this time my boyfriend started seeing a woman who is now his girlfriend. I have been really struggling with it. I feel like I am in 2 half relationships that have nowhere to go. Especially my older one. I feel like my partner has too loose expectations for me to feel secure. He is all I just want relationships to form how they do. I have talked to my boyfriend and he is working on figuring out what those are for him.

My problem is that I am having a really hard time adjusting to this new person in his life. I am feeling pushed out and lonely. I love both of these people especially my boyfriend but I feel like I am at an impass. I have not always had the best relationships, and both feels healthy but incomplete. Is this a normal stage of poly? And any advice on what to do.
