Well,
I'm guessing you're in your teens.
To be perfectly honest, most guys (and most girls for that matter), don't take relationships very seriously at that age.

In many ways, this is actually a good thing....

When you're young, you're just starting out and figuring out how to deal with "the opposite sex". Young folks take the experiences they learn and build on them....

and to be honest, just because you're going out with someone, doesn't mean either of you are "tied down".

You'll both have plenty of time for that when marriage comes around someday....
