OP, I think you'd find it worthwhile to go to a few different churches and see how you find each one. I don't like the flag-waving worship style either - I don't think there's anything wrong with it, it's just that I personally don't find that it does anything to bring me closer to God. I'm much more comfortable (and therefore, find more joy and peace) in a more sedate service.
Find a church where you feel joyful, peaceful, hopeful, and generally where you come away wanting to love other people as well as you can. There's no harm in trying out different styles (though also be prepared to compromise - you won't find a perfect church no matter how hard you look, so at some point you need to decide to commit, get to know people etc).
Divorce is separate from that, I think. I can't think of many mainstream denominations which will outright frown on divorce, particularly if the relationship is abusive. Most are happy to remarry divorcees (sometimes with the exception that they won't conduct a marriage which began with an affair).
By "mainstream" I mean things like Church of England, Methodist, Baptist, Presbyterian, Salvation Army and so on - there are also lots of independent churches (where someone has set up their own church but it's not part of any wider organisation and therefore not subject to any oversight - some of these are fine, but there's also a lot of scope for them to be abusive).
Someone suggested counselling as well, and I think that's a good idea. Not necessarily Christian counselling, just regular counselling with someone who is experienced in the issues you struggle with.
