I really feel for you!! I am so happy to hear that you found what you were looking for in the Quran. As for your husband, no doubt that is probably the #1 complaint from people about Islam that it has "so many rules", but once you know in your heart it's from God, and it's for our own benefit it makes it much, much easier. All the rules are really for our own spiritual and physical well-being.... covering, not eating certain things, no alcohol, praying so many times a day. I think some scholars say that every, single rule in Islam has a benefit. It is GOOD. Even things like capital punishment, but we don't always know what this benefit or goodness is.
Anyway I'm sure that's a discussion you can use with your husband
As for the rulings about women converting while their husbands do not, you would have to talk to some trusted imam and scholar about it. I know recently there have been some more in-depth studies with some different answers and solutions about it that you can perhaps look at.
Some might even say it's better to 'live in sin' than to deny God. I know if someone said to me, "well i can't practice everything right now like wearing hijab or fasting every fast or doing certain things, so should i wait until i'm perfect and can do everything before becoming Muslim." I and hopefully everyone would say NO Don't wait!! No one is a perfect Muslim, even people who are born Muslim, or who have been Muslim for 80 years and yes it can be a struggle, but this is the right way. It is the good way, the best way to live. You don't have to be anything but true to yourself.
As for your family perhaps it's better you don't have these political/religious discussions/fights with them. Sometimes it's better to give them time and let them see by example how Islam has changed you. Honestly I know friends who have been Muslim for years, married Muslim men and have kids and still their father or mother refuses to see anything except the 6 oclock news where muslims are blowing things up or whatever. Sometimes you just have to accept you won't ever change their thoughts and that's fine, you should treat them as your family and be kind to them as usual.
I think the best thing you can do is try to meet more Muslims at that mosque near your work, maybe you can make some friends there and start interacting with people. Maybe if they have a class or something you can just stay after work and attend it and then go home later. There are also tons of Muslims online. There's every Muslim groups from changing diapers to being second wives! There's websites, blogs and chats and message boards. And you can make friends here too. Many of the people on this board have never met, yet we have been friends and support for each other Alhamdulillah for many years. There's books and cds and conventions and conferences galore, enough to keep anyone busy
Good luck inshaAllah and we pray for you the best
