Screwing around with my dad's friend

Don't jump on me please this feels like a real love story! First he is not close in age to my dad he is 5 years old than me I'm 22. They met at work when I was 17 years old, I liked him when I first met him but I couldn't read him so I didn't know if he felt the same. He was super polite and respectful

It started when I went to visit my dad, he had a little gathering with this friend in attendance. They partied all night, I fell asleep on couch, woke up in the middle of the night to get some water my dad was passed out upstairs he was cleaning up. I asked him about my dad's drinking and it got better from there by the end of the week he had me bent over the dryer we've been inseparable ever since. It's both lust and infatuation its still growing

We've been messing around for a year and a half now I just found out I'm pregnant 🙃 and I have nexplanon in my arm. He is terrified to tell my dad and so am I but we have to. I feel like it's no big deal, he thinks my dad will kill him. I haven't told anyone, everyone around me is messy asf
