Can he get over me easily

My bf of 1 year and half and I broke up Bc his mom wasn't my biggest fan and literally convinced him things wouldn't work (were 17 almost 18). We've broke up once before Bc fighting a lot, but this time things were great. Last time he completely flipped, for a week or two he was so cold and barely talk to me. And he's the same way now. I just wanna be friends at this point, and maybe if things are different in the future then try again idk (which he liked that idea then 4 min later flipped and said we have too much history ??). We almost dated in 9th grade but didn't, but he came back. I'm so scared I lost him forever. I just want him to come back, even as friend.
