I have always felt close to my Fiances younger brother. He is always super nice to me and supportive of our relationship. He has been dating the same girl for 4 years. His girl and I began to grow close over the years. However my fiancé and I moved across the country two years ago. Enevetably my self and my fiances yonfer brothers girl don't talk as often. But this past year especially she rarely answers my calls or texts. I feel like they have both made an effort to distance their selves from my fiancé and I. My fiancé has discussed his disappointment in the change in his relationship with his younger brother. He says he feels like his younger brother is easily manipulated by his girl. I have always stuck up for her until now. I am sadden that she makes little effort in our relationship. But I've let it go... maybe I'm too needy? 

Yesterday she (fiances younger bros girl) face time calls me three times in a row. I was so happy to finally hear from her ... I call back and she tells us she's engaged. I acted really happy, holding back my feelings of disappointment and jelousy.  She later sent me a text saying "sorry for getting so emotional on the phone I'm just so happy". I said "of course you are! I couldn't be happier for you. I'm so excited to have you as a sister". 

She NEVER responded. Now I can't help it - I feel the most disappointment I've ever felt in my life. It would be different if she made an effort or recognized our (my fiancé and I) kindness. But it's like she has made such an effort to distance her self now I want her to just back off. She's all "we can plan our weddings together". 

I already feel that my soon to be mother in-law likes her more. The younger brother is the favorite child amoung 3 boys. Her family is also wealthier than mine and I'm sure her wedding will be far more fancier. I don't care about having a large or expensive wedding, but my point is ... she will have her time, why can't she let us have ours? 

Despite my frustration and let down, I know the right thing to do is fake my happiness for them. However, I'm considering asking them not to get married before us. We set the date for September of next year.  What do you think?  Is that a rude request ?
