my friends never showed 😔

2 years ago I had a baby shower. I invited all my friends and coworkers. I was so happy and excited! It was finally my turn! I had lots of family show up but only 1 friend and no co workers. I tried not to take it to heart but when I get invited to their events and always show and see the people I invited showed to these other events I still feel kind of hurt but I've never said anything. 2 years later I am having my daughter and my fiance's family gives me a shower since this time it's a girl. I invited all the same people. This time not a single friend or coworker came. Only family. I kept a smile bc I am so grateful and blessed that my family loves me and my kids. I feel like they could tell I was upset about my friends. Some of them even said they were coming... when I messaged them "Hey we missed seeing you on Sunday hope everything is okay 😊" not a single person responded to that. I'm getting married in May and my mom asked for my guest list. I honestly don't know who to put. I want to ask 3 of my friends to be in my wedding but they're some of the people who never showed or never responded. I get that we are al busy with work, family, and life in general but I make sure to never miss a gathering/event/birthday when invited by someone I love and care about. It's not about the gifts. I just wanted to see my friends and celebrate something in my life with them. Now I'm just saying why even bother. I love my family. I love my kids. I love my fiancé. Im realizing now that I really don't have any true friends. I've just been a door mat. An extra present giver for them or their kid. A free convenient babysitter. I wish I had friends who actually cared about me.
