<human>: Recently I told my girlfriend I sent some bad texts to another girl. I told her the truth as to not let it make me feel so guilty all the time and for her sake I knew she'd want the truth. I told her maybe a month after it happened (overly flirtatious texts; inappropriate).

Told her last week and now she barely speaks to me in school, as far as everyone we know they think we are broken up. But she has told me she has not decided but has 0 trust in me.

I need to show her I care for only her (which I do) and win her back.
Any ideas would help. Nothing flashy or expensive looking for modest and genuine.

Can you condense the text into a few key points?
<bot>: Need to make up to my gf and prove shes the only one i care about or dumped at the end of the week.
