is it unreasonable to be mad at my boyfriend for this?

[I as in I]

My boyfriend keeps adding all these hot chicks on facebook. EVERY ONE OF THEM are really attractive, 90% of them are single and they all live in his town. he doesnt like any of their stuff or comment on anything. i told him it made me uncomfortable once
he quit for 17 days and now hes doing it again. i am about to throw a fit so hard it will be seen from space. hes 33 and 2 of the girls are 17! He defends himself by saying hes trying to start a band and wants people to know about it- the more the better. he does add a lot of random dudes too- but EVERY female (about 15 girls a month, 3 out of the fifteen are in a relationship) is SUPER attractive- thats not so random if you ask me.
to be fair- after i confronted him the first time he tagged me in a status "Going to see Amon Amarth with my awesome gf B~~~~ M~~~"then told me if it made me uncomfortable hed stop.. and he recently changed his profile pic to one of both of us. BUT STILL, all these girls posing slutty or in bikinis hes adding. do i have a right to throw a fit? hes also only had 4 gfs in his entire life- and im only the 6th girl hes been with... i just gotta make sure im in my right before i go bananas.. he lives 55 miles away (im up there at least 3 days a week) so i get a little noided sometimes. i tried adding a shitload of hot guys- and succeeded- He never said anything:b it makes me feel SO CREEPY adding dudes i dont know...i think he might be wacking it to their pics or something. hell if i know.
your mom uses facebook.

its much much easier for dudes to get laid when they have a girlfriend. same with girls with boyfriends
PS he doesnt even have a band started yet

who uses facebook anymore?

Well, his profile pic includes you so he 's clearly taken. And hot chicks coming to a band's show attracts guys to show up.

He is your BF, not a monk ..............your not married either, right ???

Easy up, tone down the extreme jealousy before you drive your guy away.

Honestly I think that as long as everyone knows that he's happily taken and that he's not flirting with those sluts then you have nothing to worry about. However I do kinda feel like he should take your feelings into consideration but its really nothing to have a big fight about

He's trying to get people to come to his shows! If he stops online marketing no one will go. If people see others are going to his shows, especially hot girls, single guys will want to go! Facebook isn't real. If he's not messaging these girls you have nothing to worry about. You keep this up and soon enough he will be talking to these girls. Asking the girls why your crazy, then he will see them out, while you are home crying on yahoo questions asking why your lonely and he has a new gf who isn't jealous of how many friends on Facebook he has...
