Feeling nervous & worried about my relationship, HELP!

I've been seeing my current girlfriend for the past 2-3 months now. When I got involved with her she told me she had an ex that she kept in touch with but their relationship was very unhealthy. As we got serious she told me she had a talk with him and told him that she was seeing someone and that she didn't want to stay in touch with him anymore. Apparently he was upset about this but I left it at that.

Come to find out the other day he sent her texts on her cell asking her to get back with him and wanting us to split up. She told me she never responded to those texts. This made me feel awkward and angry. We had a talk about it and she assured me she doesn't want to be with him. I told her that I will trust what she's telling me is true and left it at that.

Now, I can't help to feel nervous & worried about this situation since it happened. I catch myself wishing things would go back to how they were before this incident of the texts. It's hard for me to trust people in the first place, but now I'm having to deal with this situation and trust that nothings going on with them or that one day she won't say "OK, I'm going back with my ex". I don't want to worry all the time about this or her. What do I do? Is it possible to get back to normal?
