What can I do to get my boyfriend to forgive me?

Me and him have been together for a year and a half and a month ago we decided for me to move in with him at his parents house. So with in four hours we talked to his parents came to my house and I left with him. When I talked to my mom things got emotional n I cried all night. Things for me didnt seem right at thw moment so he brought me back home the next day. I regret coming back home because his parents said that was our only chance. And now he can brly even talk to me. Should I talj to his parents and explain to them I realy wanted us to live together? I dont know what to do. I just want us to be happy again.
