Imagine the following scenario:
Husband and wife get married. Things do not work out no matter what methods are used for resolution. Before seeking Talaq and divorce in the country, is the husband allowed to perform a search to finding another potential spouse for him (and then doing a Talaq on the existing wife)?
Morally/ethically to me it would be better to have a clean break and then start the search however there could be some "time" involved where the husband searches for another spouse but cannot find anyone therefore still "goes back" to the existing wife to try and work things out again even though they may have tried before but did not succeed.
Where does Islam stand on this matter?
