What will you do if the one you love the most, insult you the most?

i and my gf loves each other but she always compare me wd her ex bf. Sometimes when we were talking on mobile& her ex called her she puts my call on wait and start talking to him. Well the talk over in 5 to 10 mins and after that she starts talking to me again & if i ask her abt what she talked wd him her reply is always that they were fighting on why she leave him. There is one biggest problem wd our relanship is that her frends and relatives dont like this relationship. And they said her to choose one either thm or me. Due to this in depression sometimes she told me to leave her. But it is not possible. We love each other and serious about our relationship. When we meet everything goes smoothly. The problem occurs whn we were on phn. I feel insulted whn she said that her ex loves her more than me, or when he called her she puts me on hold. For the last few days, the time she puts me on hold is more than 1 hr, after that she said me that we will talk later. At that time i feel insulted and insecure. Sometimes i feel that she is just playing with me but her love and care changes my mind. What should i do ........i m serious and wants her as my soulmate.........
