i need help... 😭

okay so i had a party for my 17th birthday on sunday. my friend alex (who i have feelings for) was supposed to come but he texted me that day and had to cancel because of a family conflict. he explicitly stated that him and i could hang out this week to make up for it. so we made plans to go to breakfast this morning at 9:30. i get there and text him that i’m there and asked him if he was there yet. we both have iPhones but my texts were only sending as text messages not iMessages. i called him and the answering machine said “this is not a working number” so i texted him again because i was stating to get worried. he’s not the kind of guy to not show up without telling me. i called a mutual friend and he as well could not get a call through to alex. i’m balling my eyes out so worried about him. what do i do? please help
