<human>: I went to high school and later lived with my friend Shelley. We used to party a lot together, but also had a deep and what I thought was a genuine relationship. We lived together three years ago, and around that time I was very depressed. She confronted me once about how I spent almost every night at the bar. After a couple of incidences and examination of my life, I decided to quit drinking. This was very difficult for her to accept and she would make not-so-nice comments about me stopping. Soon after that, we both moved out of the city we lived in.

I stayed in the state and she moved across the country with her boyfriend. I visited her a year later and we had a good time. She seemed a little distant, but nothing too extreme. I didn't hear from her after that. After a few attempts to reach out, she tells me she has no time to talk on the phone and that our lives are on "different pages."

A few months ago she announced her engagement and sent out save the dates. I found out from a mutual friend that she no longer wants to be close to me because of me not drinking and that feeling that we no longer have enough in common. Also people who I would consider lesser friends of hers have been invited to wedding festivities I've been excluded from. My parents and I have been invited to the wedding, but I am no longer sure if I'd like to attend when she will not even make the time to speak to me and does not seem to have much of a desire to see me anymore.

I miss her friendship and wish I could rectify our connection. I truly thought we would be friends for life. Should I try to reach out to her again? Should I forgo the wedding and say good riddance?

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Longtime friend has become distant supposedly because I quit drinking. Should I try to rectify the situation and/or attend her wedding anyway?
