Should I delete him for Facebook?

[silly*red!]

I'm a grown up. But this totally makes me feel so immature and naive. I met this guy in college and when I met him, I was in such distress and meeting him, shaking hands with him, made me forget all of my sadness. I felt like I knew him in another life. I could tell he liked me too. Let me just tell u that eventually I slept with him. I know, big mistake. As two years went by, I'd see his carefree nature. But when I'd see him, I'd always get nervous. I shake. I tremble. My heart goes crazy. I graduated last year and sometimes I'd like his pics and comment and every once in a while, I'd PM him, especially when his cousin died. Eventually, I started seeing someone else. And now he is my bf. I guess this other guy didn't know. Way before I met my bf, this guy was PMing me about my business. So I invited him to an event. He lagged. Stayed home sleeping but as a good businesswoman, I was persistent until he came to an event with me. Thing is my bf went to. At this point I didn't think that guy liked me. I really thought he was interested in my business. He even bought some product but then I posted a pic of me n my bf on Instagram and he deleted me that day. He also deleted me from snapchat. He hasn't deleted me from Facebook. And that's where I come in. I wanted to talk to him in person so I can tell him how I feel beginning to end, but he ignored my message. I sent him a PM apologizing for leading him on where I told him not to reply. I keep having dream about him. Good dreams. Bad dreams. Sleepless nights depressing moments during the day. I love my bf. He's amazing. And I feel like a horrible person for having these feelings for this other guy who I don't think deserves me. Before I delete him, I wanted outside opinions of strangers. Honest opinions.

Should I delete this guy from fb even while sharing over 100 mutual friends? Or should I wait till he does?

Pros: he's a good friend/attentive/he's fun/handsome/he is looking for a serious relationship as he has never had a gf before
Cons: I was in love with him
I saw him flirt with my friends
He is very prideful and self centered
Major ego
Girls are trophies to him
Comes off as "Player"
