On the contrary, you and she would be warmly welcomed. Our object is to bring people to Christ not turn them away. She would be welcome to attend any and all functions. The only limitation would be that, as a non-member, she would not be able to share in the bread and wine on Sunday morning although she would be welcome to attend.
1 Corinthians 7:12-15 But to the rest I, not the Lord, say: If any brother has a wife who does not believe, and she is willing to live with him, let him not divorce her. And a woman who has a husband who does not believe, if he is willing to live with her, let her not divorce him. For the unbelieving husband is sanctified by the wife, and the unbelieving wife is sanctified by the husband; otherwise your children would be unclean, but now they are holy. But if the unbeliever departs, let him depart; a brother or a sister is not under bondage in such cases. But God has called us to peace.
I hope you have found this helpful.
