You have done a good job showing the tension between Ethan and Ashley. I wonder if the hint at a relationship is a form of foreshadowing. I'm not sure where the story is going, but I'm looking forward to see what happens next.

You have shown your characters well. You have given snippets of description to give your reader a view of the characters a little at a time as the story progresses. This is the best way to give your reader a peek at what the characters look like and their actions. Well done.

Some things to fix:
Since we were s small crowd, Ashley tried hiding behind the ladies’ backs. With her back turned away from Ethan and the ladies, she tip toed, making sure to seek coverage behind bodies with every long stride she took.

Ashley can't tip-toe and also take long strides. Choose one and stick with it. Ashley tried to remain hidden by her friends as she tip-toed away from the group.

Shaking her soft hands, Ethan saw that Ashley smiled a forced tight smile. How much he felt like spilling it all out; telling her that he was the same Ethan she knew from high school, her close friend, and once her confidant. Still holding her hand and looking into Ashley's eyes that looked like the ocean, he realized that her arm had started shaking a little. He let go of her palm since he didn't want to cause discomfort. Why is the confident girl I once knew be so reluctant?

Ethan noticed Ashley's forced smile. (A forced smile is tight, so no need to use both forced and tight to describe Ashley's smile.)
How much Ethan wanted to spill it all out; telling her he was the same Ethan she knew in high school, her close friend, her former confidant. Keeping her hand in his grasp, Ethan stared into Ashley's eyes, eyes so blue they reminded him of the ocean. He felt her arm begin to shake so he released her hand.
The words 'he realized' is a filtering word. The reader already knows that they're are reading Ethan's POV. So the reader also knows that it is Ethan who 'realized' that Ashley's arm shook. By eliminating the phrase 'he realized' you are removing a filtering word that will slow the story down.

Okay, you've lost me here:
Looking at her among women, it was hard to believed that she belonged there. Her face was still that of a girl; the fringes, blue eyes that lit up her face, and the few tiny pimples that had been along her cheek bones for as long as he'd remembered. The only thing that he missed seeing was that wide smile that had dazed him when they were in school.

When you say, "Looking at her among women," what women are you talking about? In order to clarify this, could you say, "Seeing her with the women outside the club," or "Standing with a group of women in the store." It would be helpful to the reader if I knew what group of women Ethan is comparing Ashley to.

I plan to read this entire story, and I will make suggestions as I go if I think you could add a conflict or dramatic scene.

Keep writing!
