This is really hard for me😔

Paris
Me and my boyfriend broke up 2 weeks ago. It was really bad. Ever since the breakup I've been sick as hell, sleepless nights and crying all day through the entire night. We've been talking a few days and he's decided to give me another chance. Then out of nowhere, his mother texted me off his phone, telling me to stay away from him and that me and him will never be together again, saying I never treated him right, even though I know I did and so does he, and she said that I'm not allowed to hang out with him... Just when I thought things would be okay, this happens and I don't know what else to do because I just love him so much. Someone, please help me figure out a way to prove to his mother I deserve to be with him😔 something I can say? Anything at this point it's killing me because I love him so much but his mother is standing in the way of us 😔
