Reluctant to take on private equity partner(boss)

So today my wife was talking to her boss and mentioned that we were real estate investors. He was excited enough to offer putting in half on the next deal as a private equity partner. However my wife is reluctant and quite nervous about partnering with her boss. If anything were to go wrong it would make it an awkward situation for her and I work. What would anybody else to do? Or any to give any advice on the situation is much appreciated!
