Well we all know this strategy, may appear logical and make sense but in the reality it does not work very well. It actually makes things worse.
Yes, it might, but it's a strategy that you can try in small steps. If it doesn't work or appears to make things worse, it won't be a huge deal like finding out your spouse has been having an affair for the last 5 years.
As for it not working very well, why not try it if it's your last option and the alternative is divorce, cheating, or celibacy for the rest of your life? We're talking about a choice among bad options, so this is no time for complaining about small potential disadvantages.
For that matter, as for not working out well, marriage doesn't usually work out well either. Less than half of marriages last past the 12 year. So given the high probability of a bad outcome, marriage is not recommended in the first place. No marriage, no marriage problems! Problem solved.
