What is his deal? What should i do now?

Since you no doubt won't be seeing him again, honey, why don't you just put it in your past & leave it there. You KNOW you'll be meeting new friends as life goes on, & this is ALL strictly by HIS choice. Just put it as a person you enjoyed being with at a time in your life when you needed someone & move forward with your life. Things happen for reasons, I'm a firm believer in that & that people are put in our lives for a reason, be it a season, for the time being, or a life time. I would honestly not get all upset over it, & just keep going forward with your life. I KNOW there WILL BE another person who will come into your life to take his place. Be grateful for the times you had & KNOW you'll have even more as your life keeps going forward. Best to you, honey.^
