Going back on a job offer?

I was browsing the paper a few months ago and a job offer caught my eye I was not entirly happy with my current job so I applyed. 30 hour after I sent the fax I got a call, that night I went to an interview and got an offer. I was ready to put in my notice when I did I got an offer from my current employer adding almost $350 a week. I thought about it but it was a smaller organization only 3 other employees, did not offer insurance but the hours where less and they seemed to be a very organized fast growing place.
The money I was offered was less and not even compariable by hourly wage, as much as the job was what I would love to do and offered the variety I looked for I turned them down due basically because of insurance and pay.
A few months after that they contacted me again and offered me more money. Which in the long run would be less but would be a livable amount of money. Plus I would be working at a job I thought would be more suitable. I love my current employees and was worried that this organization was paying me more then they could afford and didn't want to be in an weird situation at work or not living up to there expectations for me. So I once again turned him down. He offered me more! but I stuck to my choice and said no! He did say after that he would not be able to make me another offer for awhile if I didn't take this job now.

Now a few months later I am thinking about that job. wondering if I should have taken it. I am 20years old, insurance is not something I am in desperate need of right now and can always buy insurance for about $120 a month. I am making close to 40k a year and he offered me 35k. I would be working 9-6 instead of 6:30-5:30.

I also currently work with my boyfriend whom I also own a house with and it does have its pros and cons as well. We are perfectly happy but imagine living sleeping eating and seeing a person constantly. We don't see each other mabye 10 hours a week. including sleeping. There are times that make me wonder what it would be like to not work with him. (we met at work)

I am not happy at my job now and know that this is not something I can do for the rest of my life, is there any way it would be okay for me to go back to the other organization that offered me a job and ask of a job?? Or have I burned my bridges and should just move on.
