<human>: Can you provide a brief rundown of the text in within 3 sentences?

Okay I'm sorry for this in advance: I really need to say this. 

I'm so mad. My fiancé is telling me I'm angry about nothing but he just doesn't get it. 
Okay so me and my FH have been engaged since October of 2012. We finally set a date for our wedding to be march 7, 2015.. I told my bridesmaids and made sure they could be there at that time and was so excited to have my happy moment. For about a day. 
WELL- the week after we do this my sister tells me that her boyfriend (who is still married) will be divorced finally as of July and they are just gonna run off and get married around Christmas. Mind you this is my maid of honor and sister and best friend and she just ruins my happy. 
THEN- my other bridesmaid decides to post pictures of HER engagement ring (she's been engaged for a while too) all over Instagram and Facebook and post wedding stuff and act like this is some new shiny thing for her too. Awesome. 
THEN- my other bridesmaid decides she is going to get very distant and barely talk to me now, most likely because she is going through a bad breakup and when I told her I was getting married and needed a bridesmaid she cried in front of everyone and made me look like an asshole.... 
I went to try on dresses today and nobody could go with me... I was alone. No happy faces. 
The other night I told my mom I didn't want religion in our wedding and had to explain to her that I don't believe in god and she got pissed.  Now she says "we're gonna have to talk about this whole wedding thing"
Whenever I say anything about stuff everyone just doesn't look interested. 
It hurts my feelings so much. I feel like I'm the only one who cares and I honestly don't even want a wedding anymore. I really don't even wanna deal with this shit any longer. 
Soooooo sorry for this wall of text.
<bot>: nobody cares I'm getting married, mom is mad because I don't believe in god and I think I just don't even want one anymore.
