All perfect praise be to Allah, the Lord of the worlds. I testify that there is none worthy of worship except Allah and that Muhammad is His slave and Messenger.
If the situation is as you mentioned, then your husband has violated the Sharee'ah in three ways:
First, if he lied to you and told you that he had divorced his wife while the situation was not so and she was still married to him.
Second, forsaking you (in bed) without a legitimate reason. It is impermissible for a husband to abandon his wife except if she is Naashiz (rebellious/disobedient), taking into account the command in Sharee'ah to forsake the wife in bed; Allah, The Exalted, Says (what means): {… and forsake them in bed; and [finally], strike them. But if they obey you [once more], seek no means against them. Indeed, Allah is ever Exalted and Grand.} [Quran 4:34]
The verse includes a warning against abusing the wife if she is righteous and obedient. Al-Qurtubi commented on the verse saying: “If you are given power over them, remember the power of Allah; He is All Powerful and has perfect power over all things and creatures. So no one should oppress his wife, for Allah is ever Watchful.” [Tafseer Al-Qurtubi]
The same applies to neglecting his duties towards his daughter, and his lack of attention to her upbringing in terms of care, instruction and guidance. He is the guardian of his family and is responsible for them as stated in the relevant Ahadeeth.
Third, refraining from providing for his wife and daughter. It was narrated on the authority of ‘Abdullah ibn ‘Amr, may Allaah be pleased with him, that the Prophet said: “It is sufficient sin for a man to neglect his dependents.” [Ahmad and Abu Daawood]
Therefore, it is incumbent on your husband to repent to Allah The Exalted and to fulfill your rights over him as a wife and the rights of his daughter over him as well. It is impermissible for him to obey his mother if she forbids him from fulfilling these rights. The enjoined obedience to parents is confined to that which is permissible (i.e., not a sin); there is no obedience to a creature in what constitutes disobedience to the Creator. It is advisable that wise people from your family and your husband’s family sit with him and explain to him the gravity and seriousness of his actions. They should urge him to fulfill the rights due on him and keep you in kindness as enjoined or graciously divorce you on reasonable terms. They should also advise him to fulfill the rights of his daughter and remind him that her rights are not waived even if divorce takes place.
For more benefit that a husband should be kind to his wife and not be oppressive towards her, please refer to Fatwa 389524.
Allah Knows best.
