Husband Always on His Phone

My husband is addicted to being on his phone, he says that he is most of the time working (he is in real estate media and is always trying to find new real estate agents to build a relationship with so that he can work with them) when he is on it but I have noticed that most of the time he is not working. He focuses more on his phone than being with me. Last weekend, we went to a marriage conference and he said that he wants us to be on our phones less. I have not been on my phone that much when we are sitting down together to hang out. I’m starting to get tired, what should I do? Also, I have felt lately that I have been walking on glass and the way he talks to me is very rude and demeaning. We spoke about an incident that happened this past week and I was the only one to apologize even though I told him that I was hurt by what he did. I have had trouble in the past speaking up about how I feel with him and the things that he does that hurt me. He didn’t even acknowledge that I was hurt. Lately, he often speaks with me that he is annoyed. Please help me figure out what I should do… thank you!
