Maybe the problem is that churches don’t share and support each other like they should.
In my city the churches happily band together to put on and support events. There is also a city wide church leaders group and other things. So it’s not unusual to be in my home church and get invited to other church events etc.
The churches also club together in ministry, food banks, street angels, teen challenge, kidz club and much much more.
That way you have your home church but can support other church events too without any issues. It’s actively encouraged.
