I lied to my Girlfriend (now ex), but I did not have anything to hide.

A friend of mine, who my GF has always been jealous of, but who I rarely talked to, sent me a text saying "I miss you so much" out of the blue.

My GF has always been jealous of her, and she has been doubting the both of us do have something for quite a while now. We do not.

Me and my GF were in some sort of a fight, and we weren't properly stable, although everything was getting better. Then I get that text. I did not answer and I deleted it. I deleted it not because I have anything to hide, but because I didn't want to cause any fuss, given the timing and how unstable we were. She found out.

She lost all trust in me, and broke up with me, even after explaining the situation. It has been a week now. We are still friends, and I feel she still loves me, it's the lack of trust that's keeping her away. She still cares. She says she doesn't want to text much, but if I keep texting and if she doesn't answer, she doesn't want me to feel she's ignoring me.

She says she won't get together with me.

I screwed up. I shouldn't have deleted it, but I did thinking it was for the better. I regret it. Is there anything to do...? I don't know what to do.
