Should parents get into childhood relationships ?

So I have a boyfriend and he told his dad.I met his dad his dad was super nice, but today on January 6th 2020 his mom started texting me.she asked were my address is and wanted information about me.I felt uncomfortable.Then my boyfriend told me that his mom wanted to know my apartment number.I didn’t give it because I don’t really know anything about her.I don’t know what to do would someone tell me what I should do now?😥😰(I’m really nervous and my heart is beating so fast.)
