<human>: Can you succinctly summarize the text in 1-3 sentences?

On Saturday, I told my girlfriend that I wanted to break up with her, but I am worried that I might have been too hasty. We dated for three years, but we were having some serious issues, and I hadn't been honest with her about the problems I was having. As a result, we ended up breaking up without ever trying to fix these problems.

Since the break-up, we've been talking frequently, and she's been trying to convince me that now that I've been honest about our problems, it would be worthwhile for us to get back together and try to work on them. This is a comforting idea to me, but I'm not convinced that these problems are solvable.

One of the struggles I've been having in my relationship is that my girlfriend has a really short fuse and not much patience; she frequently gets wound up and has outbursts where she can be rude and hard to deal with. Consequently, our mutual friends have become less and less tolerant of her, to the point where after I told them that we had broken up, they admitted to me that they didn't like her at all.

While I'd love to believe that I can go back to my girlfriend and pick up the pieces, her short fuse is a serious problem and one that I don't think is going to ever go away. I'm afraid that if I go back now, we'll only end up breaking up again somewhere down the line, and it will be that much harder. On the other hand, we dated for three years, and I'm worried that I'm giving up too easily by walking away without at least trying to address the problems we were having.

As a compromise, we are thinking about getting back together for a "trial run", but I'm worried that it could be a dangerous move; if I agree to get back with her, even as a temporary arrangement, I'm afraid that I'll only break her heart all over again if I decide to call it off when the "trial run" doesn't work. But I also fear that I'll regret not taking the opportunity to fix a relationship that brought me a lot of happiness over the last three years. And what if it does work?
<bot>: I can choose to reenter a relationship that has been successful until recently, but may no longer work, or I could walk away. I don't know what to do.
