for what it's worth, my wife said that the unplanned aspect was what made it an implosion. Upon further questioning she agreed that implosions are not always the result of sin. One's world can implode by an illness or accident, for example. With young couples who marry, at least it was their choice. Also, the sin aspect seemed to play some part. However, to her it was more of how things felt. Big changes came--changes due to decisions they had not planned for but which were the result of sin. Not all changes result from sin. Not all sin results in big changes, but in this case that's what happened.
I hope I got her position right. All I know is that President Hinckley was right.
I actually think GBH is correct in saying that a youthful, rushed marriage and unplanned pregnancy can cause a serious derailment of one's life's goals, although, as many have already stated, it doesn't
have to.
My disagreement with GBH is in this - he expresses extreme consternation over this scenario and yet encourages almost the
exact same scenario in countless others - except, in their case, the wedding comes first.
My boyfriend's exwife got pregnant within three months of their wedding. They were already struggling because, like so many young LDS, they really barely knew each other because they had such a fast courtship. When they found out she was pregnant - unplanned - they were both completely devastated.
Internet Mormons almost had me convinced this teaching had changed, but I don't believe it has. I believe church leadership *still* encourages their young people to marry young, (after the mission, of course), marry quickly, and to not procrastinate having children. These children are often driven by their hormones to do just that, and then they wake up after the honeymoon and realize how difficult marriage can be, then get pregnant fast, still in school, living in a tiny apartment, financial stress - recipe for disaster.
Of course it doesn't
have to be a disaster. It does make for a rough patch. People can pull through. But so could the "bad" couple, and that certainly was not the message GBH was sharing.
