Shala, definitely double-check this before you waste time and money reapplying. If I remember your situation correctly, you entered the UK on a spousal visa and were here for quite a while before you went back to the US. Your spousal visa is good for two years and it's during those two years that you build evidence to apply for your ILR. The spousal visa, to my knowledge, won't expire just because you've been back in the US for an extended time -- where you may run into trouble is when you apply for ILR because you'll need to prove that you and Patrick have lived together for the duration of your spousal visa (though you can worry about that when the time comes -- it can be sorted).
