Is it too good to be true!? Hellp!!!!?

Ok. I'm 21. In college and a senior. So i was dating this guy for 3.5 years. I really was in love with him. iBut he was a complete jerk. He played the nice guy but deep down he was a complete fake and player. I'm what guys like to call wifey material. I love being a wifey. Anyway. we had a really bad breakup like a month and a half ago. VERY VERY bad. It's over. I've moved on. I finally got fed up with his crap. One of these guys that goes to my college. He's a little older. 26. He knows what he wants. I've known him for a year.. He sent me a message on FB like two weeks ago saying that he wanted to take me out to lunch before I graduated. I thought this was weird because he lives in the same suite as my ex. They aren't best friends or anything. So anyway...he came over one night when me and some friends were playing cards and he pretty much told me that he has had feelings for me for a long time but that he never wanted to be disrespectful. We started "talking: that night and started dating like 5 days ago. Since we started dating...I feel alive...amazing...loved...wanted...all these emotions. It's like so amazing how i feel. I just don't know if its right to feel this way after such a short time. We already have expressed that we are falling in love with each other. Its like I've known him so long as a friend and suddenly one day he means so much more to me. I can seriously see myself falling completely in love with him and being his forever. And he's told me he feels the same way. He is a COMPLETE gentleman and a REAL MAN. Am I moving too fast? Help!!!
