Is it petty to not invite my bff to my baby shower ?

Ok so I need to rant about this ! It’s gonna be long so bare with me lol so me and my bff have been friends since high school we met around age 14 and we’re both about to be 24. We were always super close I mean our lives literally revolved around each other !! Anyways I got pregnant a year after highschool with my hs sweetheart I was 19 after that our relationship when down hill never has been the same. It started off her seeing me less and I did try to see her a lot but she always came up with a excuse and then I had my baby shower for my son, I had talked to her about it so much and I was so excited !! She came to my baby shower not kidding 20 mins she came with her mom they ate and left. Why ? Because her boyfriend of about 6 months had dinner for his fathers birthday. So she ditched my shower for her bfs father bday. And also the gift she gave me was a gift her mom probably had saved for years cause it was all dusty and the box was all beat up. And money isn’t a issue for them they are rich. But you know she wasn’t working so I thought she just didn’t have a money for a gift and that’s okay. Still grateful gifts aren’t necessary. So fast forward after my son was born she only saw him once when he was a small baby she got even further from me but we kept contact through text almost daily. My son is now 3 years old almost 4 and she barley has seen him i did see her a lot more in the beginning of his first year cause I really tried a effort to keep my friendship with her I would go over her house and take my baby. My sons first 2 birthdays I did really small and she never came to them. And for his third birthday me and my fiancé did him a huge birthday ! A lot of people came and it was amazing !! She knew about his coming bday party for a long time and I actually expected her to come she texted me oh getting ready to go she lives 2 mins away from the bday party by the way !! So I waited I wasn’t focused on her messages I was so busy but later on I messaged her you coming ? And no reply it was the next day and she messaged me sorry I didn’t go I had cramps and left it as that I was pissed !! You could have at least said to me that night sorry I don’t feel good I won’t be able to make it instead of going silent. I didn’t message back and I didn’t talk to her for a month. After that we started talking again and I told her my plans for getting pregnant this year and she want crazy and went off on me that I was stupid for trying to get pregnant! I went so off on her !! She told me how can I get pregnant if o don’t even have a career etc . Really long stuff. I told her off saying she only has a minimum wage job same as me and I take care of my family ! I told her off saying how can you judge me saying I can’t have more children because I don’t have a career when you don’t even have a career and you have no kids we both get paid the same and your parents pay for all your stuff ?? I have every right to try and have a baby with my fiancé !! I may not have everything together in life I may not have the best job or career but I’m a great mother and person who takes care of her family! Plus my fiancé makes a good amount of money !! So we can afford to have another child. Anyways !! After his I told my fiancé that I’m done trying to be her friend I don’t care. She dosent care for me or respect my family so I’m done trying. She literally tells me all the time how I can be with my fiancé because he’s overweight she calls him fat, Lardo, she makes fun of him ! I’m sorry but my fiancé looks dosent make him less of a person he’s a great fiance and father to us !! While she’s still with her bf and hates him and she’s with a bunch of guys from work. And this year the only time she had came to my house was because she wanted my mom to fix her pants. My mom knows how to fix clothes so she asked if my mom could come over my house to fix her pants ! Ok I think I’m done ranting ! Lol anyways my question here is should I just be petty and not invite her to my baby shower ? I’m 16 weeks pregnant so it’s not anytime soon but either way 🤷🏻‍♀️
