Your plan will BACKFIRE so badly.
Such behavior constitutes the height of geneivas daas. The end result will be both YOU and the THEIR FRIEND’s reputations will be mud. Stories like this tend to spread like wildfire. People will avoid the two of you like the plague. You and their friend will have shown that you have no concept of friendship or trust.
You are doing your own thing and aren’t listening to your rav. You stand to lose much more than you are already missing. Your kids will never forgive you for your selfishness.
