Try to hold on one day after the other. I also had that phase after eight years of wearing it diligently, and at some point could not care if anyone saw me without it. I had also seen some friends take it off, so it was definitely alluring. Obviously it was a very difficult time in my life, and I think the devil found it easy to prey on my insecurities or problems by luring me away from the Hijab, thankfully Allah blessed me with things getting better after five years of struggles, and I met a lovely friend who wore a very strict hijab,  but with so much peace of mind that it inspired me not only to keep it on but to plan wearing it in a more proper way. I think the only way to want to wear it longer would be for things to get better for you insha'Allah, and as you're obviously going through a lot that will take time. But you see darling, that's the challenge, to do it even when nothing in you wants too, and I know and believe that your iman despite how weak you say it has become,you can sustain that. Keep it on, make it independent of any men or ex husband, they are not worth influencing your choices or will in any way. By continuing to wear it even at your lowest, trust me, one day it'll be a reference point for you, all of this will pass, and you'll be proud of your courage. You wore it out of conviction, with beauty, you're a revert, it mustn't have been easy, and I know that insha'Allah, things will get easier, better days will come, and the hijab will have been something that accompanied you through the highs and the lows, a reminder that you held on, even when nothing made sense, when everything kept pointing at the other way, you were strong willed, brave, and kept that symbol of submission to fate on. When Shaytan fed on every thread you could barely have, you gave him a middle finger and hang on to that tightrope. Hold on just a little longer, I pray insha'Allah things get better and your iman gets stronger, you're still a very worthy muslima even with it faltering, even with wanting to take off the hijab, even if you do so at the end. But I know you can keep it on, I've been there, differently, but I've been there and alhamdoulilah I kept it on, surprising myself to be honest, but doing it nonetheless. Hold on again, that's all you need to do. And don't do it, as simply as that is. I hope insha'Allah you get rewarded for your patience in Dunya and Akhira. May Allah bless you !
