<human>: Can you provide a brief overview of the text?

A little quick history, we met right at the end of her last marriage, she's going through the divorce still. I came out of a long term relationship just previously myself. We had struggled early on, and sometimes still, because our previous attempts had failed and we're both scared of it happening again. Things have been very difficult this week, I'm currently deployed, she's home, so all we have is texting and skype. 

So, our issue of trust lies with my casual friendships with girls. I know that my heart is with her and I often forget that she doesn't feel as comfortable. I've made a few mistakes that has driven her to lose her trust in me and want to break things off. My violations of her trust are:

1. I had gotten a text from a female friend, but i didn't want to talk about it, so i had said it was someone else. She thought it was because i was hiding something about the girl. 

2. On a visit to my old home, I saw my ex. I wanted to get a bit of closure and talked to her briefly over food. I hadn't told my girlfriend I was doing this until after. I know this was a bad call on my part. 

3. On the same visit to my old home, I hung out with an old female friend of mine a few days later. There is nothing between us beyond friendship, but following our hanging out, I found out my girlfriend was uncomfortable with our friendship. I hadn't told her about it before and didn't think to afterword. She found out this morning and has since wanted to break up. 

It's been a long day and there's been a lot of emotion. I want to make things right with her, knowing this is the girl I fully intend to spend my life with. I've lost her trust, but she's willing to try and work things out if I can do something to prove to her I am. She tells me actions speak louder than words, but I feel out here, all I have is words. 

What can I do to convince her I'm trustworthy?
<bot>: I am deployed and going through relationship trouble. Past mistakes piled up and lost my girlfriends trust. She's willing to work it out if I can prove myself. How do I prove myself?
