<human>: I am a 23 year old male living in southeast Europe, in a relationship with a 20 year old girl. We are together for two and a half years and have been really close friends before being a couple for about 2 years. She moved to a bigger town to study science and I followed her, found a job and we are living together since March this year. The first two or three months were absolutely terrific, we got along great, the sex was awesome, everything was working out. But then something happened to us, I do not know why, but she got bored from having sex, stopped feeling the need for it. At first it bothered me that when I try to initiate she turned me down, but after thousand of turndowns I kind of made my peace with not having sex for now. At first I thought it was because she gained some weight, we are going to the gym for a month and a half now, she lost a few pounds but nothing has changed. To make things worse, I work at an outsourcing company and we are having really bad work hours so I have about 4 hours of free time every day. It is really hard squeezing everything into this timeframe and both of us are not satisfied with that amount of time but I can not change my job easily since jobs here are kind of hard to find, my job is payed very good, and without working for a month or two I would be broke and have to move back home to my parents, which is a 6 Hour drive from where I am currently so it would become a long distance relationship which would suck and break down quickly. I have a bad feeling that I can not give her everything she wants in order to be happy. On top of that, I am not a very talkative person and find it hard to start a discussion, we talk things through after they escalate and one of us (mostly her) gets mad.I just want to turn things back they were. Please reddit, share some of your wisdom with me. How do i get her back to being the loving and happy person she was?
