Is it forbidden to speak with one's ex-husband when there is a child from him, especially if the wife still loves him despite his ill-treatment?

A woman is not permitted to speak to or communicate with her ex-husband because he has become a stranger to her. Such interaction is an opening to evil, a pretext for corruption, disobedience to Allah, and a betrayal of her current husband. She must fear Allah, sever her relationship with him, and turn to what benefits her in her religion, livelihood, and family.
