Почему отец ребенка обманывает и причиняет боль? Моя дочь плачет из-за его лжи и отсутствия

It hurts so bad wen your childs father not only gives u false promises about yal future for no reason but to also lie to their child im currently crying away from her because her dad lied and i told him to just leave us alone and stop hurting us. I have to deal with her crying and hurting for him when hes not there and im thankful for this Christmas but this hurt hurts especially when she finds out she wont see him today 💔
