I don't think so, maybe you right nad half false, maybe Issei forced himself to avoid all his children, so they will not feel losing him or even cry when he die, but what about affection  Airi and Robertina?! they both love his father, at least Kurenai respect his father he undertand why he so busy,

So, i think when Kurenai and Airi still todler Issei not so busy, so he still  have time to play and even train them at certain age, maybe Issei busy because he act as member of Gremory clan, so he can't selfisy reject what they offer, Kurenai and Airi know about this and understand completly why Issei so busy !!
