<human>: My SO and I have been together for about 3 months, however we have known each other for 5 years. There was always an attraction between us but we both held off because we both held onto the assumptions that a player. That and distance was a factor at the time. 

We both did a lot of growing up and 3 months ago hit a big low in our lives at the same time. Somehow this prompted us to talk and ended with her staying over my place for a week. It was that week that we fell in love. 

We both realized we wanted the same exact things out of life, that we vibed well, (I was stoic where she went crazy, cheesy things etc.) and that the sex was great. Last month we decided to move in together. 

The problems start a bit before this. She was telling me about her ex and I encouraged her to close things up with him before we moved up from where she was as I believed that closure is just something that everyone needs when ending a relationship. 

This however seems to backfire, as she talks more and more with him she has wavered about us a lot. Its gotten to the point where her and I have broken up and gotten back together the same night or the day after. I feel like this is my fault as I honestly just want her to be happy, whether or not it is with me, and even encouraged her to go be with him while her and I end things.

However, I can see that she still wants to be with me. I know that somehow I'm supposed to fight for her, to win her back in some way but I have never done anything close to that before. What I want to know is how to fight for her, what I should have done, what I should do to win her back from all their reminiscing. Anyone who has been on her side of this kind of thing before, what did you wish the current boyfriend would have done when things were falling apart?

Provide a brief overview of the text.
<bot>: My girlfriend is wavering between me and her ex of one year. How do I make her see I'm the better choice and will make her happy much more happy?
