Trying to make me jealous over my friend? Or what?

It started this weekend where my SO said his friend's wife had offered to do his meal prep. I felt she was trying to over step me. She ended up reaching out to me before I could ever confront her and she apologized if it seemed weird. Her husband brought it up to her and that if she had heard it like she knew I did, she would freak. She told me if I ever needed anything to let her know because she doesn't work and knows I do and am pregnant. I have a lot on my plate. I went from freaking out to really appreciating her. Yesterday, I had to hear from my SO how GREAT her meals are prepped and if I didn't know how to do it right, she would. Today, we had an argument because he blamed me for running too late and not being able to get his smoothie. He said that he had to get his friend and his wife to bring him one. I was so frustrated. I decided to reach out to her to ask her what she was doing with her husbands meals so I could do the same. Her "amazing salad"? Chopped salad out of the bag. Her "amazing sweet potatoes"? Premade Bob Evans that she said was so nasty she had to douse it with sugar. And a smoothie? She was in finals all morning. So, what is this game? Why is he trying to make me jealous over her? I haven't had a friend in years. I probably wouldn't have met this girl if he wasn't friends with her husband but ok, now I have a friend. There's other things he has said about their relationship, how she does this. How their house is always perfect. Even things about their sex life. And I don't know if he's trying to make me jealous to try and make me make better meals and do more things for him or if he's just not wanting me to have a friend. What do you think?
