for me i will very angry too.... maybe u are main dish while she is the side dish... i felt ur bf mayb have phone sex with her, mayb they both really meet up have real sex.... they could be sex partner also....
i really cannot accept my bf got such friend.... i would choose to break up with him.... coz his heart not i'm the only one.... he want to have more than one.... i really cannot accept this.... even is very hurt, but think of u both future or even further till u both get married.... he really not reliable.... if he really have another lady outside, u n his family is game over ady..... so u better think properly u should continue with the relationship not.....
