Update post about breakup

I've been broken up with my ex for 2 months now, she was my close friend before we got together as we work together and become my very best friend ever. These last 2 months we've got back together for weekends but it was both a dream for us both because we both enjoyed it but she doesn't think we would work if we got serious again so that confused things. We did this 3 times in total lasting between 2 to 5 days at a time but now the last week shes really distanced herself because she knows we will keep doing it. She started to talk to me like normal yesterday but came out saying she did love me and had an amazing time together and wanted me to know that, but I said then if she had that then why can't we be together and she said because we don't work we just kept hurting each other as we're set in different ways. We was together for 7 months and it wasn't easy, she had problems which we over come but the only way she could deal with it was to break up with me for a day before we sorted it and then I had a problem with her friend trying to get involved with our relationship.....so she now doesn't think we will ever work. I miss her like crazy. I thought I was slowly getting over her but I've realised I havnt, I really have started to struggle getting off to sleep now at night, I've always been good at falling straight to sleep but most nights it over an hour atleast before I can drop off. I also hate the fact that she's been out to have some drinks with her friend because I'm scared what if she's ready to move on and talks to a new guy while she's out. I can't get over her and I don't want to, I really want to be with her again
