You should be with someone because you want to be with them not because you don't want to be alone.

I spent most my life always with someone and I was scared to be alone but after my second fiancé I got used to it, now being alone is something I'm used to and I now see it as something I would have to give up to be with someone and now I like being alone so instead of being scared of it now it would be a sacrifice on my part to give it up. So I'd have to really want to be with someone to give it up.
