<human>: Give me the gist of the text in a nutshell

my bf and i have been dating since april last year and we moved in together quite soon after that (july) - we signed a 6month lease agreement because i own a property and it's lease agreement was ending in november last year. the idea was to move into my property once the 6 month lease was over. 

so as of this year we have been living in my property. the costs of living were broken down as follows: i pay 100% of the mortgage, and we were going to pay 50% of the utilities bills until he got a job, then he was going to 100% of the utilities. 

however .. last week he told me he was starting a new job, and the suburb that it was in was about 40 mins without traffic one way from where we live. he told me it would be easier for him to move back home and live for the duration of the job (9 months), to save money, petrol , food etc just day to day expenses in general .

i guess my first reaction was trying to be supportive. he explained to me that his first and foremost priority was to save up enough money to buy a car this year, and living so far from work was going to hinder him from doing so in this timeframe. i have tried to rationalise my emotions against him leaving. i.e. he only lives 40 minutes away, its not like it's long distance & we will see each other on the weekend. 

i guess my main gripe is i'll be wearing my mortgage and bills, living in an apartment by myself after making a commitment that he's just walked out of because it's not convenient for him. am i wrong for feeling this way or am i being a major pushover? someone knock some sense into me.
<bot>: bf of 10 months is moving back home to be closer to work due to convenience. i feel like i should be supporting him but also can't help feeling abandoned. help?
