I’ve always thought the majority of us tend to behave more responsible after getting married. And we automatically curb or stop totally some not so healthy things we previously did.
A man losses his family suddenly and becomes lonely overnight. That could push just about anyone to relapse back into whatever activity he did before and quit cause of his family. It could also push an ordinarily leisure gambler into gambling excessively.
Without any responsibility, it would easy for anyone to do as he pleases as the repercussions would only befall him and no one else.
Agree with you on this. Responsibility can help us reshape ourselves into our better version. Not true for everyone but most of the times when a man marries he takes up his family responsibilities without any hesitations. Especially the older child does this. Taking care for his families, making daily needs, having a roof under he and his families becomes the main concern. Whatever the things he did in the past before marriages, doesn't concern him anymore. As for gambling habits, it vanishes with time because he has a family to take care of. Family always comes first in term of priority.
