you people can see my history in last few threads. let me make a short note here:

my Bf says that " i will be true as much as i can .if you have trust just be with me forever otherwise let me live alone with my friends"
How can i believe him after he cheated me more. i am miserable now. still i thinks that he is having affair in his previous office. he says that " i will never talk with any girls after i did one mistake"
My doubt is
1.he had one mobile without my knowledge. but he stated that mobile is one of his roommates mobile.
2.he gave one number that belongs to her colleagues(girl) but she never picks my call . even she don't know that is my number. how she think that i might call her(may be he told her )
3.that number which my bf given is switched off after i asked why she didn't pick my calls to my bf
4.i know her personal number and i got her number from his office. but her personal number and another number which given by my bf(said that her another number)continuously going text and calling every time. i tracked by customer care.
if both number is that girl number why she chating continuously in her own number. it might be my boy friend number right????
5.he using so abusive word to me. if i asked to scold her he wont because she is innocent girl he says. innocent girl will never have affairs with another's husband .,. right??
6.my bf brother told me "that girl called his number and asked my husband to call" but he scolded her .

above all is my doubts. am i doubting unnecessarily. can i trust him to make him feel better? suggest me how to handle if any one enters relationship. can i be quite? just let him to do this things and can i wait for him???

he says that he will be true if i have trust on him.. so i am insisting him to have this affairs. i ma getting fear please help me how to handle this situation..
