I think you are seeing it perfectly clear. Your gut knows a husband stealer when it sees one.
I had a similar experience when I was newly married. A single friend I made at our rental apartment complex started asking my husband to come over and kill a spider or fix things, etc...
I told him I didn't trust her and didn't want him to go. So he didn't go.
What balls of her to bring your h a steak dinner because you went away! Who does that?
