Hey guys. My lil story then

I have been in a realationship over a wonderful year. Then my gf started to look for a job and she got one in nightclub. So allmost every night she was working which resulted in being zombie at day time or sleeping most of the day. Also working in nightclub means that she gets 10 AFC facebook requests on fb per day and every single one are flirting and asking them out on dates.
During our year together I managed those guys perfectly, was being cool with that some guys are chasing him and made no big problems about it, but when I had to watch how he was talking with those guys every day, I started to loosing my alpha and turning into more AFC day by day. I wasn't giving enough space to her and started to be needy, because that relationship has turned out to be a nightmare when I was trying to be sweet with her and all I got in return was sleepy gf. She was suggesting that we should take time off and I agreed. She also mentioned that I can kiss other women if I want to and be as free as I want to.
First days being apart was afwul and I got so fcking lonley. On the 3rd day I called one of my ex gf's and we met up in town. We drink alot and had some fun which resulted in kissing her at the end of the night.
Next day my gf wants to make up with me and I told her that I would like that too, but I need to be totaly honest with her so I told that I kissed my ex gf. That's when everything turned into shit. She wanted some days to think about the situation and I gave her some thinking time, but meanwhile I really just wanted to see her and ask how she was doing. She was still parking at my house to go to work at nightclub so I asked if I could see her when she is coming after her car, but she rejected me 3 nights in a row and on the 3rd night she was coming back with her work mate, who supposed to be friend, but I got so fcking jellous and logged in with her fb to see whats going on and I found out hat she had told to one of her best friends that she had some butterflys in his stomach with that guy and lately have not had any for me.
That happend today and I got so fcking mad and pissed off so I decided to pack up her things, told her to come and take them while I am going to my country house and told her that I never wanted to see her again. Then just when I was walking to busstation she cought me and we went to my place, talked a bit and decided to take some time and find out who we want to be in future.
Any comments will be appreciated and I would like to hear some suggestsions, because I would like to stay togehter with my girlfriend and be the alpha as I used to be, but I am so emotsional SPAM so everything is falling apart.
