Is he trying to make me jealous or something?

okk well i just started going out with this guy ,we have been talking for a while before though. i really like him alot and i think he feels the same but im just a little confuse..he makes me laugh all the time and always know when something is wrong with me even when my friends cant tell even before we met and would just be talkin on the phone.. he tells me he loves and miss me so much all the time, we talk on the phone for hours on in when we are not busy..when we are together most alot of times im all over him like huggin up on him and stuff but when im not most of the time he will pull me to him or something like that..he tells my im beatiful and y alot..really the only problem i have is at first he always talked about all the girls that wanted to have with him..and there is her ex girlfriend that he did talk about ALL the time..well it would be most of the time that she would be callin and textin him i guess but still it was like every 5 seconds(i really think he was liein to me about something)..and my last problem is on his facebook he has over 200 friends and only like 20 of them are guess(i was not stalking him he said something bout and i just wanted to see if he was lieing)
