Need help abt my relationship!!?

hii there frnds.. actually i met my gf on facebook and we live a few hours away.. but we have met few times been intimate wit each other whenever i have gone to meet her.. we meet like once a month.. frst time i went to meet her she got a call frm a guy which she didnt pick up and said its her college frnd and if she pick up it will cause her a lot of time as college frnds talk a lot etc.. she often gets texts frm other guys.. and one time again when i went to meet her some guy was calling and she didnt pick up in front of me.. but we love each other she says it too.. now am having probs with her facebook.. there was one of her co worker my gf posted some status on facebook and that wrote looking hot.. etc.. and my gf replied with zyada mat bolo etc.. but i got really angry and talked abt this wit my gf but she got very defensive.. and stopped talking to me.. i had to literally beg her to talk to me again.. and now she has hidden her facebook wall frm me which i dont like.. and she said i dont trust her but i trust her.. i mean any bf would not like if hes in a serious relationship and some guy comments on her gf like that.. i have told her numerous times very politely to unhide her facebook wall but she doesnt really seem to care abt it and never does it.. am getting really hurt by this.. and most of the times am the one who that i care a lot.. she doesnt show that she cares a lot.. any help wat should i do now??? thanks for the help in advance maties.. i really love her
