Will I get in trouble if I recant my statement?

So my boyfriend is sitting in jail because he got caught speeding and for drinking DUI, that same night before he got pulled over, I have just finished work that night and had a few drinks before he came and picked me up. Anyways he was drunk when I got in the car and we started arguing and he stopped on the side of the road so I could get out, as I got out and tripped and fell and bit my lip, so about an hour or so later after that, I went to my mother's and she called the cops behind my back and I didn't want that, so anyways the cops showed and I told them I didn't want to do a statement but they lend me in to do one anyway so I have had some drinks in me at the time and was very upset about our fight we had and so I was over exaggerating and told the police officer that he hit me out of anger, lots of mixed emotions, so now he can't come in contact me at all, and I don't want that. I messed up about lying in the statement now he maybe doing more time now because of it, I love him and want him in my life and out of jail. Will I get charged for lying in my statement? Should I talk to the crown?
