First of all, mazel tov on the marriage!
I can offer some advice.
First, you said there was a congregation near you, but your husband felt unwelcome. (What does that mean?) You did not specify what stream of Judaism it was, but if you haven't checked it out, there is a Reform congregation, Temple B'nai Israel that is in your town. Although I do belong to a temple where I live, many times I worship online with a fabulous congregation: Central Synagogue of NY. Luckily, you're in the Eastern Time Zone, so services will be at the proper times for you. The URL is:
www.centralsynagogue.org The clergy is wonderful, particularly Rabbi Rubenstein (who actually took the time to answer a letter I had written) and Cantor (and Rabbi) Buchdahl. There's at least one Conservative congregation online and other Reforms, so you can worship from the comfort of your own home. Cyberjudaism.org might have some.
Second, I am inmarried, and my level of observance is different from my husband's. The bottom line is that you've just got to do your own thing.
Third, your husband is correct. Most Jews don't care how you converted. I believe that Reform, Conservative, and Reconstructionist all accept each other's conversions. Orthodox do not, but the question is whether you forsee yourself ever becoming Orthodox. While I'm partial to the Reform branch (I'm third generation Reform; the last Orthodox in my family had come from the old country in the 19th century), do what's most comfortable for you. If you're not going to be completely observant, I doubt an Orthodox Bet Din would convert you, anyway.
Best of luck.
