Poll: How do I convince my girl to accept my Facebook relationship request?

We're in a private relationship. I have a strict policy on being in a relationship. That last one started like this. One day I was in gym doing the early workouts with the cl. This girl never gets dressed for gym all she did was go up to the bleacher after attencdance was tooken. So I was doing a workout I looking rolling her tongue in and out at me. I was like is she into me? Then she said she had another bf and she wanted me. And then one day I got happy and told it out. Then next day people were in my face laughing at me. She didn't claim me as her bf. That's why I have a strict policy on PR's. So, this girl I'm with she's most things I want in a girl. She's a virgin, she's nice, cute and friendly, not disrespectful. We been together since last Saturday. I asked her this 2 days ago do you love me she said she don't know. So Now I asked why are we in a PR? she said idk. So I asked are you embarred to be seen in public with me? She said yes, becasue her friends would not talk to her. So, I asked would she accept my Facebook relationship request she said she don't know about that. But she did just prank me that we broke up. I was soo embarred. Thank god it was by text tough. But I'm still with her because we had the same situation. Boys were hurtin her and girls were hurtin me. No girl ever looked my way or gave me a chance. Boys just had her and threw her away. So, I asked her out and she said yes but don't tell nobody. I was on board because we both wanted to take this relationship 1 day at a time. I'm still with her because she the only nice and cute girl I can get a I STRUGGLE to get girls. I don't think she'd play me though she seems loyal. She text me unexpectedly
