How to get rid of annoying friend who was once a bff??

Need some advise. I had a very close friend since I was 5 and started kindergarten. We remained close until about we were 15. I moved to another country and we stayed in touch through letters. I met her when we were 21 and I hated her. She became this snobbish person who loved talking about money and expensive buys. The time we were apart her dad started a new business and became millionaire. So it showed in her personality. We didn't attend each other's weddings as we both got married just one day apart which was a relive as her wedding was all about designer clothes and money spent and I had very simple wedding. She has never worked a day in her life and I have been working since my teens to meet ends. Luckily my husband and I worked very hard for everything and now we live a very comfortable life. Recently she and I had babies few months apart and she made some very stupid remarks on my Facebook announcement. (She said she cannot believe it I am so fertile at this age. I just turned 35). Well fast forward 12 years and we are currently in the same country and she is driving me nuts by calling me and sending me messages to meet up for coffee. I have provided with every possible explanation so that I don't have to see her but she is just not leaving me alone. Last time she started calling my family members so that i can meet with her. And she ended up coming to my moms house. This time I really don't want this spend 3-4 hours with her and listen to her stories of riches. (Every time we speak it's about her new house, her new car, what her maid did or how she has to listen to her chauffeur). Don't think I am jealous of her and her money. I'm actually least bothered. I have far more rich friends who are so down to earth and act normal. I asked her why she wants to meet. And she said oh I just want to see how you look !!! 😳. So please tell me how to make her leave me alone. Thanks !!
