I think someone from teasung's family members (most likely his grandfather) told haebom that taesung will not be able to take over the company because he won't produce an heir. Heabom, obviously feeling very hurt, was torn between 2 options: stay with taesung and take away his chances to own the company, or break up with him to secure his future. The first choice is selfish and the second is heartbreaking. He feared that telling taesung would corner him into choosing the first option instead of it being a choice of free will. Not knowing what to do, he ran away hoping that he would be able to sort out his feelings and get over him with time.
That's just my theory though, but it would be annoying if it were really true. I mean they are not exactly strapped for cash, and money was never an issue in the whole series so why now?? Also they are married, so if anything, this plot should've been adresses waaay sooner than this point in this story
