We did not know you could sew in the first place! God, I whis theives loosers new how to spell and hughes the english language.
Now if you meant sue-who did you indend on sueing? Your boyfriend or the truck that "you hit"? If the truck driver was at fault-like he/she turned directly in front of you or if they crossed into your lane-definately. If your boyfriend actually hit them for any reason other than they failed to yield the right of way, then no.
Now if you want to sue your boyfriend because of your injuries and he is being a jerk and not paying your medical bills then go for it. You have the right to get compensated for medical, lost wages and pain and suffering, take your pick or take all. Do not look for a quick settlement. These things drag on for years.
