Am i going too fast finding someone new!!!?

yesterday i asked a question about me catching my boyfriend (ex) in bed with someone else, i wrote the whole story... anyway.. there is this guy that kind of been my secret admirer since i was in the relationship with that guy who cheated on me, i mean we only stared at each other, check each other out and never talk or meet up close, so my little brother is a friend with his little brother and he goes to his place sometime downloading movies on pendrive, i walk out on my cheating boyfriends since saturday on sunday i got all my stuff out of his house and move to my mum's , and on Monday i told my brother to ask my secret admirer for his phone number and he gave it to him to give me without hesitation and since then we have been chatting nonstop, last night we met late at night, we only talk and get to know each other more, before going we kiss and say good bye, but i can't get him out of my mind since then, i find myself smiling or laughing without reason!! do you guy think i'm going too fast? should i wait for a while be single for sometime? i don't know but he is nice, sweet, the opposite of my ex and i liked him since a long time ago.. what should i do...please no insult!!! thanks
