I need good advice. Women please read!! Im heart broken and in pieces What to do when Fiancee and I break up?

I had been with my fiancée for five years, and engaged for the last year and a half. We were perfect for each other in every single way. She told me on a daily basis, that she doesn’t know what she would do without me. Three weeks ago she said that she was unsure about what her feelings were for me, and she knew she loved me, she just didn’t know if she was “in love with me.” She said we needed to take a break, to work on ourselves. When I did hear from her, she texted me late into the night, and we had a conversation for about an hour and a half. Then we decided we needed to get together in a couple of days to exchange belongings. When we got together to exchange things we were both really upset and emotional. We kissed, and then made love twice, and spent the whole afternoon together. She said that she feels at home and safe when I am around. And we had agreed that we would work out our issues together, and that we would just take it slow. We also talked about the things that have been an issue to each other in our relationship. She said, and I will admit to, that she felt like I didn’t care about us anymore. She felt distant, and she felt that her needs, and wants, and opinions, were not important to me. And I will admit that, and it hurts more than I could ever put into words. She also didn’t like that I complained about my job for over a year, and hadn’t done anything about it. And that I had put off my health, and that I had done nothing about it even though we have talked about it, also she didn’t like the fact that I wasn’t taking my college seriously anymore. After all this, she told me a few things about her. She said she started to smoke pot, again, a lot. This had been an issued when we first got together. She quit for five years until, about 4 months ago, when her sister moved back. And since then, she said she had been doing a lot of it, behind my back with her sis. She then told me she would quit forever. I think that she was doing it because she was feeling displaced because of us. Another thing she said was that her sister was coercing her into a lot of the recent decisions that she has been making. Her sister doesn’t want me around. The reason being, is because when I’m around, my ex never wants to spend time with her sister. Anyways, she agreed not to hang around with her, because she is such a bad influence. Then we made arrangements to see each other, then, before she came over, she called and said that she felt like the whole thing was a mistake, and that she still doesn’t want to see me. So I didn’t hear from her for a week, and after that week we decided to get together, and exchange a few last things we had. Well, déjà vu happened. Again we agreed to take it slow, and she said that she was sorry. We seen each other every day of the week and were happy together again. We made love every night, and had serious, quality time together. Then after we spent three days together, I left after we made plans to see each other this week. I haven’t seen her in four days, and we had been talking to each other every night. Something that has bothered me though, is that she hasn’t been talkative, and slightly distant. And then this morning happened. This morning she texted me, saying how excited she was to see me tonight xoxoxoxo., she had made plans for her to come over, I have been conscious not to pressure her and let her make her own decisions.While I was at work, she called my mom (they are close), and said that she wanted to break up with me forever. She said that she doesn’t love me anymore, and she doesn’t feel anything when we kiss. She told her all about her feelings which you already know. Then she sent me a break up text. It hurt so bad to read, I can’t explain. She doesn’t want to talk, because she says she doesn’t want to lead me on, and she doesn’t want to hurt me anymore. We had to talk though to make plans, to cancel her phone off my account. She wants to cancel her service, and get a new phone, and number and we have plans to take care of this. She has yet to tell me if I am going to get her new number or not. I just don’t understand how her thinking and reasoning can be so erratic. She wants me more than anything in the world when I am around, but when im not there she is so confused about us, she doesn’t even want to give us a chance. At this point I am taking the situation as is, and am trying to look to the future alone, even though it is nearly impossible to consider. My questions are where do I go from here? Do you think even if she eventually wants to work things out?Do you think she loves me still?Is it bc she is afraid ill fall back on my promises? Do you think we will ever get back together? I need help, I have been sobbing all day regardless of the mistakes she has made recently, she is the most important thing to me. It hurts so bad, bc all she wanted from me was to improve myself, for myself, and I didn’t do it or realize it till it was too late.
