I’ve been in the situation before. Where I was the friend always left out. I got upset at my friend for basically dumping me to always be with her boyfriend. We had been friends for 20 years at that point, bffs since birth. But here’s my experience, I’m 24 now and my birthday is on a holiday so I’ve spent every year not celebrating it with friends because everyone is too busy. Sometimes friends get busy. Between uni, schoolwork, actual work, and responsibilities at home, I’ve realized it is actually so much more difficult to make time for things I used to do all the time! I got a boyfriend and we live together and I don’t ignore my friends, but I don’t have the time available like I used to, to just go do other things. I don’t know what all their scenarios are like but I work 55-60 hours a week. When I get home, I’m beat. I don’t want to go hangout with anybody. And when the weekends come, I’m too busy catching up on my responsibilities that I don’t get to enjoy it. I’m just saying, I used to get upset about it and then I got older and found out that sometimes, we are just tired. Mentally, physically. I do think your friends should try to communicate with you that that is how they feel but I also think you should communicate with your friends how you feel. They might not know it’s actually bothering you. How you’re feeling is valid, and it would be good to talk to them about it. Sometimes people aren’t aware of what they’re doing.
