No, your spouse is not required to file for Bankruptcy just becasue you did. You have the option to file as an individual, even if you are married. However, there can be negative consequences if you and your spouse have jointly owned debt or property and only one of you files for Bankruptcy.
Married individuals must gather the following information about their spouse regardless of whether they are filing a joint petition, separate individual petitions, or even if only one spouse is filing.
In a situation where only one spouse files, the income and expenses of the non-filing spouse are required so that the court, the trustee and creditors can evaluate the household’s financial position.
