Idek what to do

I just need to rant. My bf has a shitty mom and she tears him down, the whole damn mental abuse shabang. Today I saw him, he was happy, living life, just talking and showing me so much love. Then as soon as her bitch ass comes home she messes him up and now he’s saying “I can’t feel anything, I can’t even feel love kind of. I just appreciate the presence kind of” and I’m trying to be supportive while he’s breaking my heart especially after everything we did today. It’s like was it all fake or what? I don’t understand, it hurts to hear him say he can’t feel love but I’m trying to support him in his time of need. But he’s always in need, and I feel like a bitch for feeling down casted when his life is constantly in shambles. I just don’t know what to think, I love him. I do, I’m so happy with him. But I wish he would see I’m doing everything I can for him, it doesn’t help he’s pessimistic as all hell. I’m just kind of upset that after the affection he gave me and all the sweet things he said and did, he’d say something like that. I’m sure I sound insensitive but I have no one I can talk to about it, I don’t tell him how I feel because I think that’s just awful with everything else he’s dealing with
