I literally had this exact thought!I haven't watched her vlogs since Lee came into her life but I've always got the sense she's forcing their whole love story and her asking him for a baby proves that to me.
It's like she's in a race with someone... Simon? He got engaged she one upped him with a baby
But also I feel like she's competing with everyone ie thisanothergirlslife who recently gave birth and even herself. She's 30 and probably feels like this is where she should be in life. She was calling Simon her fiance with no actual engagement then look what happened. So she latched on to the next guy who stuck around.
Even her saying she's always wanted to be a "mama". Seems like anyone who fit the bill would do...
Babies can make or break a relationship so it will be very interesting to see how this plays out...
