I cant just get him out of my life, but i love my family!?

i grew up with a boy in spain, and hes gorgeous , and we are like soo so close, and he makes me so happy, i mean hes is extraordinarily romantic, he leaves roses on my doorstep with little verses, he listens to me all the while and vice versa, and we've had great times, well a few months back , he asked me to go to egypt with him , and i did just me and him , whilst there we were on a road trip to the pyramids, and he asked me to marry him in front of everyone, i was so shocked becus we dont even go out, but i said yes, becus i truly love him . but my family fell out with family a couple of years back , and now they are saying i cant marry him , and that if i do then there are going to be problems, i cant cope with this , if i cant be with him , its going to hurt so much ,
