Friends falling off ?

So in my friend group, I’m usually the one who makes plans so we can all meet up and hang. Which I do feel like at time I wish they did it. There is one who each week we keep moving the date to hang out because they keep making up excuses at first I was like okay they are busy but at this point they are avoiding us and I’m not sure why. And now I said we would hang this weekend but another friend (in the same friend group) canceled and it’s just like why do I keep pushing to spend with people who don’t even make time for me OR IM BEING SENSITIVE and need to chill
