Guy I like with another girl on Snapchat feeling crushed 😢

I have really liked this guy but it’s still early stages as I met him a few weeks ago. We talk every day and have had some cuddles/kisses and a bit of foreplay at my house but not sex yet. He has come out with my and my friends. Anyways he is at a festival this weekend a few hours away and posted a snap with another girl with his arm around her and tongue out as if licking her face with the caption ‘festivity buddy’ Not happy at all 😢😢 feeling pretty crushed that’s he’s with another girl no doubt he would get with her

Any advice / tips how to not feel like shit over stuff like this ? Anyone had similar experiences ?

When he gets back if I keep seeing him should I ask him about it ? Thanks xxx
