I feel like dying

I found out that my boyfriend's mother thinks that my boyfriend should " start fresh" and that she doesn't love him anymore because he has changed since we got back together. Because he spends so much time caring and being with me. ( I see him twice a week if I'm lucky). This thing is he has to pick between a mother's love or me. If he picks mothers love, its not a break its officially over. If he picks me I'll break a mother-son bond. I'm trying to be supportive towards him and making sure he picks the right thing. I mean I truly adore him and I want the best for him. I want him to be happy. If it's me that needs to be subtracted then so be it. I can't be selfish. Right now I feel like dying inside. If he goes I'll lose myself!!

What do I do?
