Does he have to support me and pay for housing during my iddah?

أَسْكِنُوهُنَّ مِنْ حَيْثُ سَكَنتُم مِّن وُجْدِكُمْ وَلَا تُضَآرُّوهُنَّ لِتُضَيِّقُوا۟ عَلَيْهِنَّ ۚ وَإِن كُنَّ أُو۟لَـٰتِ حَمْلٍ فَأَنفِقُوا۟ عَلَيْهِنَّ حَتَّىٰ يَضَعْنَ حَمْلَهُنَّ ۚ فَإِنْ أَرْضَعْنَ لَكُمْ فَـَٔاتُوهُنَّ أُجُورَهُنَّ ۖ وَأْتَمِرُوا۟ بَيْنَكُم بِمَعْرُوفٍ ۖ وَإِن تَعَاسَرْتُمْ فَسَتُرْضِعُ لَهُۥٓ أُخْرَىٰ

Lodge them [in a section] of where you dwell out of your means and do not harm them in order to oppress them. And if they should be pregnant, then spend on them until they give birth. And if they breastfeed for you, then give them their payment and confer among yourselves in the acceptable way; but if you are in discord, then there may breastfeed for him [i.e., the father] another woman.

حَدَّثَنَا يَحْيَى بْنُ يَحْيَى، قَالَ قَرَأْتُ عَلَى مَالِكٍ عَنْ عَبْدِ اللَّهِ بْنِ يَزِيدَ، مَوْلَى الأَسْوَدِ بْنِ سُفْيَانَ عَنْ أَبِي سَلَمَةَ بْنِ عَبْدِ الرَّحْمَنِ، عَنْ فَاطِمَةَ بِنْتِ قَيْسٍ، أَنَّ أَبَا عَمْرِو بْنَ حَفْصٍ، طَلَّقَهَا الْبَتَّةَ وَهُوَ غَائِبٌ فَأَرْسَلَ إِلَيْهَا وَكِيلُهُ بِشَعِيرٍ فَسَخِطَتْهُ فَقَالَ وَاللَّهِ مَا لَكِ عَلَيْنَا مِنْ شَىْءٍ ‏.‏ فَجَاءَتْ رَسُولَ اللَّهِ صلى الله عليه وسلم فَذَكَرَتْ ذَلِكَ لَهُ فَقَالَ ‏"‏ لَيْسَ لَكِ عَلَيْهِ نَفَقَةٌ ‏"‏ ‏.‏ فَأَمَرَهَا أَنْ تَعْتَدَّ فِي بَيْتِ أُمِّ شَرِيكٍ ثُمَّ قَالَ ‏"‏ تِلْكَ امْرَأَةٌ يَغْشَاهَا أَصْحَابِي اعْتَدِّي عِنْدَ ابْنِ أُمِّ مَكْتُومٍ فَإِنَّهُ رَجُلٌ أَعْمَى تَضَعِينَ ثِيَابَكِ فَإِذَا حَلَلْتِ فَآذِنِينِي ‏"‏ ‏.‏ قَالَتْ فَلَمَّا حَلَلْتُ ذَكَرْتُ لَهُ أَنَّ مُعَاوِيَةَ بْنَ أَبِي سُفْيَانَ وَأَبَا جَهْمٍ خَطَبَانِي ‏.‏ فَقَالَ رَسُولُ اللَّهِ صلى الله عليه وسلم ‏"‏ أَمَّا أَبُو جَهْمٍ فَلاَ يَضَعُ عَصَاهُ عَنْ عَاتَقِهِ وَأَمَّا مُعَاوِيَةُ فَصُعْلُوكٌ لاَ مَالَ لَهُ انْكِحِي أُسَامَةَ بْنَ زَيْدٍ ‏"‏ ‏.‏ فَكَرِهْتُهُ ثُمَّ قَالَ ‏"‏ انْكِحِي أُسَامَةَ ‏"‏ ‏.‏ فَنَكَحْتُهُ فَجَعَلَ اللَّهُ فِيهِ خَيْرًا وَاغْتَبَطْتُ بِهِ ‏.‏

Fatima bint Qais reported that Abu 'Amr b. Hafs divorced her absolutely when he was away from home, and he sent his agent to her with some barley. She was displeased with him and when he said: I swear by Allah that you have no claim on us. she went to Allah's Messenger (ﷺ) and mentioned that to him. He said: There is no maintenance due to you from him, and he commanded her to spend the 'Idda in the house of Umm Sharik, but then said: That is a woman whom my companions visit. So better spend this period in the house of Ibn Umm Maktum […]

A woman in the iddah of a revocable or a final divorce does not leave her home at all, by night or by day. Both the divorced woman and the widow keep the iddah in the house where it began and do not leave it, unless she is put out, the house falls or she fears it will, she fears for her property, she cannot find the rent, or similar necessities; then she moves to the nearest place.

وَلِلْمُعْتَدَّةِ الْمُطَلَّقَةِ) بَائِنًا أَوْ رَجْعِيًّا السُّكْنَى وُجُوبًا عَلَى الزَّوْجِ

A woman in the iddah of divorce, final or revocable, is owed housing by the husband as an obligation.

تجب سكنى لمعتدة طلاق ولو بائنا إلا ناشزة ولمعتدة وفاة في الأظهر وفسخ على المذهب وتسكن في مسكن كانت فيه عند الفرقة وليس لزوج وغيره إخراجها ولا لها خروج … قلت: ولها الخروج في عدة وفاة وكذا بائن في النهار لشراء طعام … وتنتقل من المسكن لخوف من هدم أو غرق أو على نفسها أو تأذت بالجيران أو هم بها أذى شديدا

Housing is owed to a woman in the iddah of divorce, even a final one, unless she was rebellious (nāshiz). She lives in the home she was in at the separation; neither the husband nor anyone else may put her out, and she may not leave. She may go out in the iddah of death, and so may a finally divorced woman by day, to buy food and the like. She moves from the home out of fear of its falling or flooding, or fear for herself, or if she is harmed by the neighbors or they by her, severely.
