^It can change in a matter of seconds. Calm down and reflect over things. In any relationship…you need to develop a certain level of tolerance…and learn to let some things “slide”…as well as give the benefit of the doubt. Pick and choose your battles. If you make everything an issue…you’ll drive yourself up the wall…and destroy your relationships.
Your father (regardless of how he interpreted the computers comment)…would not have been hung up over this comment for eternity. He would have eventually moved on from it. As upset as he may have been…he wouldn’t consider your FIL’s question a “dealbreaker” for the rishta.
Slow down. Before rushing to accuse your fiance of having insensitive parents…see if there may be other reasons behind someone’s comment. And then evaluate if it’s that big of an issue. If you do have an issue, approach it with some tact.
If your questioning “breaking your engagement”…then you need to think about whether you’re ready to get married.
