Why do people always stood me up?

So most of the time I wanna meet up with people (some I know from uni, some from old workplaces, online connections) for a drink/hiking/dinner etc, they reply pretty positively, like "Yea would love to" but then always postpone it or cancel it.

to make it clear, I dont text people constantly, I do watch out to not become annoying, but I seem to do something wrong.

I am open minded, can talk freely about a lot of stuff, can be emphatic, I am no self entitled a**hole.

Though I have always had issues to get friends since I am shy and I got bullied, talking with 1 or 2 people is no issue to me but when its a group its harder.

Now especially as an adult who is close to finishing uni (mostly work from home, assignments, no courses) I think its even harder to make friends, or even have anyone to talk to about random stuff, like movies or travelling or so. Just feel freakin lonely
