Eye colour is due to multiple genes, not just one. A useful model for understanding eye colour inheritance is consider it due to three genes. Each person has two copies of each gene giving six "alleles" in total, and each allele can be for either dark or light, with the dark dominating the light.
Eye colour then depends on how many dark alleles are present:
light blue - 0 dark
blue - 1 dark
green -2 dark
hazel - 3 dark
light brown- 4 dark
brown- 5 dark
dark brown 6 dark.
You have either 4, 5 or 6 dark, your boyfriend has either 0 or 1.
Your child will inherit 3 alleles from each parent -- any combination of 3 from the 6 available. From you, there will be at least one dark and possibly 3 and no more than 2 light. From your boyfriend, there will be 0 or 1 dark and at least 2 light.
Your child's six alleles then will include at least one dark and at no more than 4 dark. So your child's range of possible eye colours will be blue, green, hazel and light brown.
They can be any color from blue to brown, including green and hazel.
It's probably going to be brown. Brown is the dominant gene. However you didn't go into your grandparents. blue is a recessive gene, but can be carried down through generations. I have brown eyes, my husband has blue. My parents have brown eyes, but my one grandfather had blue. My daughter has blue because I was evidently a carrier of the blue gene.
That takes me back to first year genetics. Too long a procedure to write out here but here is a website that can calculate the odds of each colour for you.

OK well I think, unless your carrying the blue eye allele gene (what is possible depending on what your parents carry), That it will 100% brown even if your boyfriend is carrying the blue allele. As Brown eyes is dominant.
Brown + Brown=Brown
Brown + Brown=Brown
Brown + Blue=Brown
Brown + Brown=Brown
Those are all the possibilities if you carry 2 brown alleles
However if you our carrying a blue and brown allele it will be like this:
Brown + Brown=Brown
Blue + Brown=Brown
Blue + Brown=Brown
Blue + Blue= Blue
This means you will have A 25% chance it will have blue eyes.
But of course there are still the possibilities of getting green eyes and combination of colours, which are very hard (if not impossible to predict).
Hope this helps
genetics...dominant and recessive
B=brown
b=blue
ur mom is Bb/BB and ur dad is Bb/BB
u got either Bb/BB
ur boyfriend is bb
there is a 25% chance that ur kids will be blue & 75% that they will be brown
