Well, if you go to different churches that kind of makes everything a little bit more complicated. The bible says under Matthew 18 that if you guys can’t resolve this after taking a couple witnesses before you’re supposed to take it to the church. Well, back in the time that Matthew was writing, the church was essentially the community, and so in modern day times if you have two different churches, my first bit of advice would be to have both of you take it to your respective pastors. You have to start there. They may or may not be able to resolve it, in which case you should come to a neutral third party, someone who is perhaps versed in Christian conciliation and how to do this and resolve the dispute in the same biblical manner that your church should be applying to the situation.
