It is unfortunate that people are just that people, some (good vessels of honor) and some bad (vessels of dishonor.) Never forget that all in church are not saved this is why we must stay focused on God and not man for man will sure fail you.
As for your question about what should you do?
Well that is dependent on your relationship with God.
1 Seek God for an answer.
2 Seek God for an answer.
3 Oh yea, seek God for an answer.
Peace
