my girl who i had a ten month relation with has a male friend infact her best friend he is. recently she told me that she was plannng to go to his aunts place as she is a dancer and had a show there. i told her it would be wrong as u have a team there and stay n food is taken care by the choreographer then why stay at his aunts place. this offended her. then she says she might go on a alone trip with him to a destination... though i wasnt keen and put forward my perspective " do u think going like that is right?" she feels that i dont trust her. i know she might not go but still when she said i gave my honest opinion. she put up similar hypothetical situations and now the relation ended. i called her friends many times trying to figure out if i was at fault and shared my issue with them so that i could know why calls me possessive and insecure and jealous. she also says i show off that i trust her but thats not true i do trust her. shes says if i go out for full 24 hrs with him u might feel it wrong and if u see me in the same house with him u will still not trust me...where i cleared to her that as ur companion i might get irked at that sight but the trust factor is still there.
pls advice.

PS: i am single first timer and she is a soon to be divorcee. we planned on marrying after her formalities and were in deep love and these issues werent there before . ever since her male best friend knew me and i gave her a ring as a token of commitment ...these issues arised.
