Possible to get ex back?

Hi, I'm trying to get my ex girlfriend back and here's the story.

So me and her went out for 4 months until I said something stupid and broke up with her. But later I realized my mistake and asked to be with her again. I guess after that broke up, she felt really hurt and cannot be in a relationship with me anymore. But after giving her hugs and kisses, we got back together and things were going pretty well again. Until I had to move back to my own country and we stopped talking for a while.

I know in the meantime she has gotten another boyfriend but recently broke up with him. Now that I'm back to where she is, I really want to get back with her. Recently, I asked her out a few times and the interaction we well. But I'm sure she only looks at me as a friend right now. I'm wondering if there's anything I can do to get her attracted again? Please give me some advice.
