For starters, I'm sorry you had a bad break up. Those suck.
I'm just trying to make sense of your story here, which is... with all due respect there's a lot not making sense.
As i said earlier, some details are missing out and some are slightly changed for privacy concerns. if one of the guys at my chappel happens to come across with this i dont want him saying "wait... the new guy had the exact same story! he must be the undercover guy!" as my country is already visible, so that might be muddying up the story, and i'm sorry for it, but i wont stop doing so for privacy.
the core of the idea is I arrived at the chappel after having had close to a month of introduction to mormonism 101 by my gf, her main points were the first vision, and how the church fell away, why Joseph was a true prophet and some history of the church, also some cultural stuff, like activities, and the structure, what was the BoM, D&C and so on, also some about the pre existance but not much, i didnt know much of christanity so it seemed odd, but hey, i knew nothing, for all i knew the pre existance could be a very normal and established thing.
Be mindful, we were in a relationship, so its not like we spent all day talking doctrine, but rather regular old dating stuff.
First day, all goes well, and I'm approached by 2 gals from the US, they offered me to be visited by missonaries and sit down for a talk, i thought they ment like a "welcome to the gang, lets hang out!" and frankly, i declined bc of living with my parents, not being home all that often and so on, fast forwards 4 months later, they are still tiptoeing, when talking about exaltation, they would never refer to it as such, but as "getting to be in the celestian kingdom" or "reaching the third degree of glory" I was given by my gf a book on the principles of the scripture, and in class, i would question some of it but i would be met with responses that today i wouldnt accept as they are out of context or not supported by the bible, but at the time i didnt know much better, so it seemed off but alright, keep going.
4 months after that, they dropped that round about language and by the time i was leaving. they were at that time openly talking about the preexistance in more detail, about temple ordinances, about baptism for the dead, how the BoM says salvation is faith + works, about sealing in the temple and so on...
Thats the short story, I then leave, my best friend tells me my gf is spewing bs about me cheating and how my gf did actually cheat, later we break up, and even later my "best friend" turn and denies such claims once i finally leave the church for good and my "best friend" in turn gets baptized into the church (she entered the church about 4 months before), also, as i begun leaving and finally left for good, "friends" started not replying to messeges and finally ignorning me.
if you wanna know a little bit more detail, PM me and i can provide some, but the gist is, I experienced that way of hiding some stuff from the outsider at first, and while the lessons by the missonaries could have gotten me up to speed fairly quickly, i dont think any church should hide its beliefs and let a few do all the work, I also experienced the shunning afterwards
