Is it permissible for my husband to spend time with his ex-wife without informing me, and is he obligated to provide financial support to her similar to the support he gives to his children? The level of tension between my husband and me regarding his interactions with his ex-wife is quite high?
Your husband is not allowed to maintain any form of contact with his ex-wife, as she is now considered a stranger to him. Furthermore, he is not obligated to provide financial support to her, except during the Iddah (waiting period) as prescribed by Shariah. However, it is important to note that he remains responsible for supporting his children at all times.
