Help w Family While Eloping

Hi everyone!
I could use some advice/tips on dealing with my family.
My fiancé and I always knew we would never have a “regular” wedding. We’re socially awkward, home-body, introverts who get incredibly stressed and anxious with gatherings, so we knew eloping would be our perfect bet! We’ll be flying to Scotland in April to elope, and we couldn’t be more excited!The problem is, specifically, my mom…She and I are incredibly close and she sees me as her best friend. I love my mom, but I think she’s having a difficult time acknowledging that I’m starting my new family with my fiancé and she always tells me how much she misses me, sometimes in tears. My fiancé really wants our elopement to be just the two of us, since adding guests makes it feel more like a performance and can be distracting (I feel the same), but I feel like I’m crushing my mom’s heart by not inviting her… Should I tell her we’re eloping (where and when) beforehand so she can emotionally adjust? Or should I wait to tell her until after we're married and then explain? I’m scared to talk to her about it because I know she’ll cry and it always guilt-trips me…I want to include her somehow, but I’m not sure how. Any advice would be so appreciated as I’m just not sure what to do. To those who eloped, how did you deal with close family?Thanks in advance
