This is just total ego mania. It seems more an extortion for presents than a desire for weddings.
She should just get civily married to ensure the child is legit and then either have a VERY fast wedding they can afford or just wait until AFTER the baby is born for the religious ceremony.
I really get the "gimme presents" vibe from this.
Most weddings seem to be overblown affairs these days, these women are no different than most in that respect.
I don't even think most are big ploys to get presents, really, thousands more is spent on the wedding itself these days than they will get in presents. It's just a fantasy that sucks women in... The desire to have the gorgeous designer princess fantasy they see in wedding magazines. It gives them an excuse to spend six months to a year deciding on flowers and napkins and typefaces and play dressup.
Myself, I was never keen on the Princess Plan. Many friends tried to involve me in theirs and many tried to get me to care about napkins on my own. We did throw a fantastic party, truth be told, but I tried to keep it just that, a party everyone would actually have fun at.
