Please help me figure out what this dream could mean...?

I recently dreamt that I was going to get married with my boyfriend, though in the dream we were only really good friends kinda like best friends ( I think) though we weren't romantically involved. in the dream he told me he was in love with only one woman & he wanted to marry her then he blurted it was me, I also wanted to marry him, from what I remember it seemed like I planned my own wedding & everything seemed perfect till the actual wedding moment, I didnt have a dress, my aunt suddenly appeared offering me a dress to wear but when I put it on I distinctly remember it being dirty- dingy like it was old. It had an off white color with black trimming & black satin around the waist, the dress wasnt ugly but it did seem very old, dingy & had black on it. To me; my own personal superstition: black is a very bad sign for a wedding. but back to the dream though I wasnt too happy with my dress I wore it & when it came down to walk down the isle he wasnt there, I remember calling him on my cell & he told me he was @ a bar playing pool trying to distract his mind cause he thought I didnt want to marry him, I then told him i did & that we were all waiting for him,he then told me he was on his way happily. I somehow then met up with him and we walked back to the venue together and we seemed happy. but thats it thats all i remember, I dont remember actually getting married or anything else. This dream has been lingering in my head & has been bothering me, what could it mean? first of all we've only been dating for 7months, we dont even live together yet so its way too early to be even thinking about marraige, we are very happy from where I see it.. so what could it mean? & Y am I really focused on this dress? the dinginess & black has me worried, if anyone could help shed some light on this Id greatly appriciate it!
