I want distance from my husband!

For months now my husband has been distant and pullling away, he used to be affectionate and loving and walk talk to me and treat me like his wife - but now I feel more just like a friend. Especially when he called me bro and bruh all the time 🙄 it breaks my heart. I've told him, I've told him how I feel. He knows, he is aware of how he is being and how things are different- he said it will change and he will make an effort but so far nothing. We keep having the same fight, going round and around.  At this point all I want is to pull away from him now, I hate being the only one giving affection and making an effort. I hate craving his love all the time and getting nothing. I feel pathetic and desperate. I want to be how he is. I hate this.
