How do i get us back to the way things were?

[bayboy]

I've been dating a girl since September. She became my gf in novemeber. I upset her by liking pictures on social media until mid January. She found out in February, and Now she doesn't trust me. We've been together since, but she says she doesn't feel the same. She's brought it up a few times since, and I understand her being upset. How do I get help her to get passed this, like I said, I don't think she's at fault, but how do I get her to feel the way she felt about me before?
