Parent acting different since engaged

Hey all! Has anyone else noticed a change in their parent's behavior since becoming engaged?My mom absolutely adored my FH & always spoke so very highly of him before we became engaged. Now since we're engaged it's like she is a different person. She's skeptical of how much money he has. (He was about to take over a well off family company so it's not unreasonable him having money, especially with two different degrees and two masters.) She like literally tells me she doesn't believe it. She also has become very intrusive about his schooling & keeps asking about how expensive my engagement ring is. She did none of these things before we were engaged and now it's like she is skeptical about everything. I'm not sure if it's because she is trying to play the dad role since my dad passed away before I met my FH? It's driving me nuts. She is purposely trying to get me to doubt my FH. She also had two divorces so maybe she is scared for me? I have no reason to doubt my FH and no red flags.
