feeling kind of jealous? should i make a big deal out of a FB account?

[me]

well, we have been together for 3years, he moved to Italy six months ago and i'm moving there with him when we get married but i want to get a master's degree first.
even though we live in two different continents we managed to keep our relationship very strong. He calls me at least 6 time every day and we talk all the time via msn.
He tells every time he calls how much he loves me and that he can't wait to get married. He even calls me when he sees a cute baby and starts telling me about and how much he wants to build a family with me. He buys me a lot of clothes and stuffs and he even sends me a lot of money every month (which is equivalent to a salary and saying the money and i'm going to use as a deposit for a house or something like that). he is paying for my visit to Italy (hopefully in june). He doesn't drink or smoke and he hates stuff like clubbing and partying.
I love him with all my heart and even more since he's gone.
The problem:
i don't have a FB account coz i hate it. My fiancé has one and he has a lot of friends (300) and a lot of them are girls . He told me about it and said that he is using it mainly to get in touch with other bands and to expand his clothing line ( he just started it).
should i make a big deal out of it ?? i don't know, i can't stand looking to those girls??
BTW i'm 22 and he is 28
ooops just noticed some missing words.
and i mean i'm saving the money not " and saying the money".
sorry
