Crushing on my first kiss and last school year's Makeout pal

Omg so this hot ass (sorry for the word but seriously he's that hot) guy was my low-key make out buddy last school year and we've flirted a lot since Feb but omfg have so started catching the feels so bad. He was my first kiss. We never dated and my dad wouldn't approve for the longest time but now he gave me the okay to date him but the guy has a girlfriend now! It totally sucks! It doesn't help he's a bit of a player.
