I gave him my number, didn't reply to his text and now I feel bad?

I'm 18 and have been a hotel bartender for a week. Yesterday a 24 year old guy (hotel guest) came and talked to me for 3/4 hours and we got along well. He asked if I was working on Tues (today) and then if wanted to go out for drinks with him on my day off and I said maybe. Later he asked for my number and I gave my real number to him without thinking straight…

10min after he left he texted me saying "hi --, thanks for talking to me all night, you're a nice girl. X"" and coincidentially my iphone died that night and I lost all data and when I restored it in the morning, his text/phone number was gone.

Anyway, he is staying till Thursday and he came into the bar today when I was on my break and sat in the back of the bar so when I returned I saw him with his back to me. When he finished, he got up and strode out and glanced at me when he walked past me. Ouch. I guess he got the message of me not replying but didn't even acknowledge my presence. I feel bad but is it my fault my phone died?

You have to tell him what happened! Right now you look like the bad one so he is just like ignoring you how you ignored him! Even though it was on accident you still have to tell him!

Not your fault, if you see him again call him over and explain it apologetically and say something cute asking for his number again, after explaining what'd happened.

If you actually like him then you should have said to him what happened. By you not going up to him and telling him makes it look like you are not interested at all.
