i love my fiance! And we both now have stable full-time jobs in our industries with healthcare and everything (finally-4 years out of undergrad, 2 years after we both finished our graduate school programs, and 6 years of dating later). We got engaged last summer and were hoping to get married next year, however, my fiance's mom is now saying that she thinks we are moving too fast; she thinks my job should be closer to his (we are hoping to live in queens or so, since his job is where he is from on long island, and mine is out here in central jersey, and we could each do a reverse commute); and she thinks we should push the wedding back a few more years. My fiance tells me this last week and for some reason, he is aligned with her

and is hoping to move our wedding back to 2015. I told him it breaks my heart, because by then it will be 8 years of us dating when we finally get married, and that if we keep waiting, there will always be an excuse and our happiness and excitement to be together will never be allowed if we keep waiting to satisfy everyone else's wishes. I don't know what to do-I'm thinking of breaking off the engagement this weekend and telling him that 2015 is far too long of dating (and it would end up being a 3 year engagement!) and that, despite my love for him, I am marrying him, not his mom.
Why is this happening to me? Most of my friends who have gotten married, my family, and others I know of don't have this problem with their FMIL. She even had the movie "Monster in Law" on last weekend when we were visiting, and his other brother was trying to stoke the fire and make cracks. What do I do??????
