Reconnection with ex?

My ex fiance and I have been officially apart for two weeks now. We were together for five years. Our relationship has been on the rocks for about a year now. For the last year, we have been growing apart. I had fallen into a rut, from not taking care of myself physically, to not taking college serious, to being a jerk for a while now, and not taking her needs and desires seriously,and complaining about my job. While she gave me hints of her unhappiness over the last year, she never actually took the time to sit down and talk to me about it. And smoking pot, a big issue, she used to do, and recently began to do with her sis again, she claims she has quit again. she also hangs with her sister and her friends constantly, who are bad influences, and wrong people to ociate with. Also, something that has worried me. Is that her sister introduced her to a friend, right before we broke up. I know he wants my ex. My ex promises me that he is just a friend, and is not her type (which he is not), and she is not interested in having a relationship with him or anyone else. I doubt anything will ever come of it, bc he gets drunk all the time, and smokes weed constantly, but has also done cocaine before, which she cant stand bc that is the reason why she never met her dad, and the very reason why she hates her dad ( you can see how these people are the wrong crowd). This upsets me, bc they txt each other constantly. So, this is so confusing bc its a side of her I hadn't seen in five yrs until her sis moved back home. We both agreed, even through the turmoil, that we were the loves of each others lives. During our on and off period, she said that she still loves me, and we would make love, and hang out. And when I was around, she loved me dearly, but when I am gone, she starts to have second thoughts. She agrees that the reason she recesses in her thinking about us, is because she is afraid that I will go back on certain promises of change that i need to make in my life.We had three weeks like this, until last week, when she finally just decided to cut ties for good. The next day I dropped things off to her, and she wasnt happy to see me. She did cry, she said that she was very upset about the whole situation. Then this week I had gone over to her house to drop the last of her belongings off to her. After I did, we made love, and hung out .She had told me that she felt sooo good to have me around. She said that her heart is in it, but her head isn't right now. She said that she doesnt want to be in a relationship with me, or anybody for that matter right now. And she needs to take some time for herself, I need to do the same for my own reasons. I know that she isn't interested in seeing anyone now for a fact, bc she wasnt "well groomed". So anyways, there we made love again. And she said after we hung out that I needed to go take care of my stuff for the day, as does she. But she said, it wouldn't be the last time we seen each other, just for a while. Then today she txt me that "feels love for me", just not the way that i do for her. She said that over time, her feelings disintegrated and that it happens to everyone. The she said, "Your a wonderful person, the same person i could see myself together with forever" what does that line mean? Her brother, although never engaged to his girlfriend, went through a same period in their relationship. They eventually got back together and are now engaged. They didn't see each other for a while,and she used it as a reference in the txt. She then said how after a while they gave it another go and then said "I honestly cant say when that time will be for u and me, but I dont regret anything from yesterday." And yesterday we hung out for a while, and made love, which is what she was referencing. She said that at this point, she is moving forward in her life, but still wants to be friends, because we have always been best friends. She said that she never wants to loose the bond of our relationship. She then said that she had moved on (which hurts to hear) and that she grew away from me.I txt her back and told her to keep safe, and out of trouble. That I also want to remain friends. Then I said that we need to work on our friendship with one another, because when we were at our best, we were best friends. And recently we became live in enemies, and didnt accommodate each other. She agreed. She is the reason why I have already begun such important changes i my life.your thoughts
