My boyfriend behaved rudely due to his female colleague now wants patchup what should i do?

I have been in love for 6-7years. my bf is working out of town.. he told abt his friendship with a female colleague. but later i found that girl interferring . i was nt comfortable with their daily unusual talks without any reason.she was behaving too personally by tolding him abt open zip of his pant , going to his house where my bf live alone,asking and wearing fav colors of my bf, i asked my bf to make a distance and dnt call her as she is colleague. but he didnt and behaved rudely with me and told that he will nt stop talking to her.she talked with me 0n phone indecent manner when i called her. she asked my bf to not reveal all their talks as i was getting annoyed. all this was happening when my bf was out of town . he told me all on phone. i have again asked that his colleague is behaving too personally. this is nt fair make distance from her but he blame it my possesiveness.now my bf is in my city wants to patch up with me &told many odd things abt that girl. ex she wept for him
