Of course its not all about just working things out. I meant they fell in love and things worked out as a result of that. Meaning they got married, had children and now are very happy Mashallah.
Yes, it makes things easier when there is a common language between people. They can laugh, share jokes, humor, etc. But that doesnt make the love between people who dont share common language any less. Does it? If both speak English fluently then how is “i love you” less effective than “mein apse blah blah”?
