I know that people mean well when they advise, but the reality is that they do not live your life and they have no idea what you will face and they certainly will not be there for you when (and if) you face any difficulties.
I would caution you to take it very VERY slowly. First you need to wait and hear back from a scholar who can guide you on what to do about the marriage part of things. Marriage isn't as disposable as people make it seem today (astaghfirullah). Allah clearly does not like the dismantling of the family unit, divorce is his most disliked permissible act. So, please,
figure yourself out before you give the news to your husband.
You also cannot emotionally blackmail anyone into accepting ANYTHING, let alone a religion or faith. When you present your new faith to him, you also have to present him with options because this will affect his life as much as yours. Marriage is a partnership and you already made the decision to accept another (life changing) faith without him, so in my estimation, the least you can do for him is take it slowly and warm him up to the idea. Write down the things he objects to and find a way to gently and lovingly show him otherwise. Don't rush any of this
I'm a fellow convert by the way. It's been 13 years for me. Trust me when I tell you that you will be tested in your declaration of faith and it isn't going to be easy. I strongly advise you to study and gain some conviction before making any announcements. It is very painful to lose family and being alone. That's a reality many many converts face and when they do face this kind of hardship, they begin to feel negative towards Islam.Those people who once rushed you to declare to the world that you are a Muslim are nowhere to be seen when this hardship is faced lol. I'd like you to avoid a scenario like this, insha'Allah.
The truth is, that we are in control of how we present ourselves, how we present our faith to those that are not very familiar with it. In order to do this properly, we ourselves have to be well familiar with what we choose to follow. People need time to come around and some never do. Be prepared for that.
With much love and understanding,
your sister in Islam <3
