Break up

My boyfriend just dumped me because he said we went to fast and our relationship wasn't exciting yet we were only together for about two weeks but we did go fast and to me it's BS but I am really sad because it took a lot from me to open up to him and now I feel like a slut for sleeping with him and I should have know this was coming  just I need some support so I'm looking here for for it. He even blocked me from Snapchat and it hasn't even been an hour since he he dumped me
