<human>: A few weeks ago My girlfriend of 2 years broke up with me. I was destroyed fro a few days but a girl that I've known since kindergarten reached out to me. She helped me through the break up we hung out had coffee and she just all around helped me forget the break up and made me happy. One night me, her and her friend went out to dinner, my ex texts me yelling at me because she believed someone that told her that i said some terrible things about her (i never did) this pushed me away from my ex and made me get over her quicker, the same night me and my friend had a spark. we both felt it and after that we both fell for each other. Fast forward a few days ago me and my friend are talking on the phone, She says she loves me and i say it back (I know super early we both get it) we go back and forth but in my 1 am tired haze i say, I love you [insert ex's name here]. i didn't even realize i said it, i said it out of habit from the 2 years. Now she doesn't trust me, we're friends but she doesn't trust me. she can see us together but we decided to take it slow and i have to earn her trust back. for the weekend me and her are taking a break from talking to think and we'll be talking on monday about everything. but what i'm asking is advice on how to have this girl trust me again? i understand it'll take time but I'm just looking for input. me and her were really close and told each other everything. but now it's just meh. we'll be going to prom together but again i'm just looking for ideas to help me out.

Summarize the given text in a few sentences.
