Yes. Stop thinking you're so old and past it silly girl. You're only 22. Widen your circle by going to more places and more different types of places if you are concerned.
If you're not married by 22 it doesn't follow you won't ever be. Pull yourself together
And the causing fights thing, wellll some might say you have a fear of intimacy or commitment - whatever. Take some time to think about what it is that makes you do that and talk to your friends; people that know you.
