What do you think about this?

I recently tried having a heartfelt conversation with my girlfriend about something she does that bothers me (telling other guys she loves them). I recently had to move so I also tried telling her that I wanna interact with her through more than just texts (phone calls, webcam, etc.) because I really miss her voice and the fun conversations we had. Texting, to me, is okay but after many days of nothing but texting, it gets dull. She got really defensive and sarcastic, like always, saying she doesn't like talking over the phone cause she's always busy or with friends and that she can't promise a webcam date because stuff always comes up. I managed to keep my cool but after an insanely sarcastic comment, I got irritated and said that whenever I try to have a heartfelt conversation with her, she gets pissy. I then said I felt like, just as she had felt a while back, that I couldn't be myself with her due to this. Well... She got pissy when I called her pissy, and said "f*** you, I'm done with this petty s***." I apologised for calling her pissy but not for telling her how I feel. She responded with "okay." I said good night cause I knew space would be good for us. This always happens. She'll try to say I'm changing her when that's hardly the case or she's just being herself. All I'm trying to do is get her to maybe make more tine for us, like I always do. I compromise, she doesn't. I feel like if she truly valued this relationship, she'd wanna put in her share of it. Am I right? What do you think?
