I need her back.

[BWM]

Me and my ex have been split up since April of this year, since then we have had many arguments on the phone through text messages and facebook which has made her parents hate me. This ended around a month ago and we have remained in limited contact since and have been getting along okay. We met up a few days ago and it was great she says she miss's me but hates me at the same time but the game changer happened when she told me some news and judge upon my reaction would determine if we can remain in contact, my reaction was good and she tells me ive grown up a lot since back in the desperate days when i kept texting her and phoning her etc. All i need to know is how do I get her parents back to at least like me again so then this would work because I need her back and we both still love each other in a way, I'd really like this to work as she is my first love and im not ready to let go yet, so please any advice would be welcome, thanks
