Search Results: he says things and then push me away

Me and my girlfriend had been together for about 5 months now and our relationship is very complicated. I really love her and think that she is the one, but i know for a fact that her heart does not belong to me. She is a international student that came from China. She broke up with her ex because she was coming here for school, it hasn't been that long since their break up, so i know she still has feelings for him, its understandable.
But the thing is that if she has decided to be my girlfriend then, i think she should respect me and at least try to forget him, but instead she would talk to her ex everyday and night video chatting. We had a fight and i made her send pics of us to together to her ex and apparently they are not talking anymore and cannot even be friends.
These 5 months that we have been together was amazing. I can honestly say that they are the best times of my life. But it also saddens me that these 5 months I have yet to feel her love for me and the role of being a boyfriend. For the past 2 weeks she had been very depressed, I wanted to talk to her about it, I wanted to console her, but it seemed like she didn't want to see me. She avoided my kiss and pushed me away when i hugged her.
My theory is that i think that when she came over to Canada she felt very lonely and just wanted someone to be with and that happened to be me. Her mom is good friends with my mom so she is staying at our home, but my mom told me that she didn't want us being together.
I asked her many times if she really loved me and wanted to be with me and she said yes every time, but i do not feel like she does. We never talk on the phone, she never holds a texting conversation with me.
I don't know what to do right now. Should I continue to stay with her and hopefully one day she will truly love me, or just let her go? I really love her more than anything. What should I do? I'm planning to meet with her this Friday with my final decision.
