Need some advice please.

this girl that used to be my best friend threatened to call DHS on me after I had my first child bc she left some clothes at my house that I didn't know was there and couldn't find and stopped talking to me completely. but now I'm pregnant with my second child and she's best friends with my boyfriends brother and she decided to tell my boyfriend that she would "let go of all the wrong I did her" and "put it in the past" just bc "she wants to be there to hold the baby" when she's born. my boyfriend got mad at me for being mad about this and I can't seem to figure out why. mommies what would you do in my situation.? do you think this is wrong.? bc I don't want her anywhere near me or my kids bc if she can threaten to call DHS on me when I haven't done anything wrong what should make me think she won't do it again.? right.? just need opinions please.
