loner:
(also ‘lone wolf’; plural: ‘loners‘; for the right pronunciation, please click here)
a person who spends or likes to spend most of his/her time alone, and avoids to be in group with other people — spends time all by him/herself and does not like to be with others,
a loner enjoying the peace all by himself
e.g.
We know that Beatrice is a loner, and every one of us has tried to get her into our circle of friends without much success.
Some experts say loners are harmless and over time they join others, at least in some activities, but some others say that loners tend to be violent and may involve in murder or rape.
There is a strong stigma attached to loners just for liking to be by themselves — loners are often treated as weird or disabled.
Compare: introvert
