Told my dad about this guy I gave a blow job to

I've been kind of depressed. I've never done anything sexual before I met this guy in Edmond Oklahoma a couple weeks ago, I gave a blow job too... And after I left he never talked to me again... I've only ever had my dad in my life. Mom walked out when I was a baby. Me and my dad live in an RV and travel because he's a traveling photographer. Back in Oklahoma he did a wedding and we were there for a week and a half and I got a guys number... We texted and I really thought he liked me... After nearly 3 weeks I knew he wasn't gonna talk to me. I guess my dad figured something was wrong so he asked and I said nothing. He ended up climbing on my bed and offered me a donut he said he knows something is wrong and to tell me. I said he will not want to hear it and he said he just wants to help. So I said "I gave a guy a blow Job" and he almoat choked on his donut. He said "Wow... Uh okay." I told him we didn't do anything about else but he stopped talking to me after. I expected his to be mad but he just put his arm around me and said "That's the sucky part of life. You meet assholes". He told me that I'll get my heart broken and it's part of life. I asked was he mad and he told me " For what? Being a teen. You're gonna do things and make a million mistakes. Everyone days. But you get up. You can be sad but still get up. What's his name?" I said his name. I told him his name and he said "The guy from the Wal-Mart? You are not gonna let a guy with a forehead tattoo make you cry". We ended up finding a place to go night fishing. I love my dad
