Tithing is a sensitive issue

Ever since I stopped tithing in November last year, my local church seems to be 'on strike' by printing out the leaflets every 2 months instead of every week. How much can they save this way? Now I don't know who the speaker will be for next week and what the topic will be. They also started putting donation envelopes in every pew that makes it so obvious! And the message is now more on law and works instead of grace and God's favor. I need to save the money for my retirement but I still give offering. Some people don't give at all but that is their business. Sometimes I wonder, did I give to the right church?
