Is my bestfriend done with me?

So me and my bestfriend have been friends for 5 years we grew up together and recently we've been going thru a lot of changes first I moved in with my boyfriend and he takes up most of my time but I always make time for her and I always bend over backwards for her to make her happy and yes she helped me with some finances and viceversera we've helped each other and then she got her first boyfriend and she started acting funny but I let all that go because that's her boyfriend but I gave her advice when she asked he treats her bad like really bad . but fast forward a year Im getting married she's my only best friend she didn't through me a bachelorett party or anything but I let that go then I left for Rhode island to be with my fiance and and I wanted us to go out one last night but nope now im married already knew she couldn't come because she couldn't afford it but she never respond now she told me she going thru a lot that's why she couldn't respond to me but we always had up and downs we got into a argument and now she hasn't responded to me in almost a month why. What do I do I miss her she's like a sister..
