Feeling Out the Loop

I’m 26 (f). I had a solid group of 5 good friends in highschool. Slowly we separated over time, jobs, college, moving away, boyfriends, new friends. I’ve tried to rekindle with them, but it always seems like they reply “yeah whenever!” but never hit me up first and then nothing ends up ever happening. So i’ve stopped trying. All I have is my boyfriend, he has a solid group of 3 friends from highschool he hangs out with, talks to, goes on trips with, even little things like cruising around or going out to eat with them. I have none of that anymore and I miss my girl friends so badly, yet it seems they’ve all moved on and don’t think of or miss me. It makes me sad to imagine big events in my life and having no friends to invite, such as a bridesmaid at my wedding or things of the like. I’ve met people at work, text only one co worker girl friend often but we don’t hangout. I just feel so out of the loop. I hate that this happened. Everyone tells me that’s what getting older is, people move on and you usually just have your bf/gf/ life partner. However I miss those days laughing with my friends doing nothing. It hurts to realize it’s all gone. Anyone else going through this? Just wanted to vent
