It is incredibly odd…isn’t it? So many words saying very little.
To OP, I think it would help others to give you advice if you say exactly what sort of plans you had that didn’t work out. Plans not working out come in all shapes and sizes, and advice for one thing doesn’t necessarily apply to another.
If it’s a relationship you seem to desire, then asking for more relationship focused advice may be more fruitful than vaguebooking and not getting much in the way of useful responses.
