Even fuck buddies are difficult

Been hooking up with this guy for a week or so, we established that we just hooking up for fun, just wanted to find one consistent good fuck buddyWe were supposed to hang out last night i hit him up to see if he was available but

no answer but he finally opened my Snapchat around 10pm and never even responded back! Should I message back to see what happened or leave it as is? I don’t want to make it seem like I have feelings for him or whatever. I hate being annoying and double texting.
