This summer you’ve got big plans to unwind at Fire Island. And your fingers are crossed tight for a makeout sesh with a dreamboat.

Then the heavens break, and it happens.

You meet an incredibly hot, smart and funny creature, and you spend an amazing summer night together.

But what will come of this “relationship” when it’s back to reality?

Use the guidelines below to determine whether your fling is just that, or has long-term potential.

Don’t judge a book by one makeout.

It takes time to really get to know someone, because no one is completely candid on the first date. It may seem obvious, but to find out if the attraction’s more than physical, you’ve got to stop making out and start talking.

Make sure you’re comfortable.

When the lights are out, it’s easy to let loose. But does the feeling remain in the morning? If you’re not comfortable before you’ve spruced up, it’s probably a bad sign.

Talk, talk, talk.

It all feels dreamy when you’re sharing tequila shots. But how’s the stone-cold sober conversation? If you think there’s potential, don’t be afraid to ask questions. “What’s your favorite book?” “What motivates you in life?” “What’s an amazing compliment you recently received?” If you remember their answers, and they remembers yours, you’re on a solid track.

Get scheduling.

While we would never endorse inviting your crush to your sister’s wedding, making future plans can be a good thing. Play it cool by passively mentioning a movie that you’ve been dying to see. If your hookup expresses interest, thumbs up! But if they avoid the idea, you may want to rethink things.

No matter what happens, we’re all for summer lovin’, so we urge you to get out there and start flirting.
