Feeling lost in my marriage

I'm 32, married to my husband for almost 6 years together for 8 and have a 7 year old daughter. Husband has Adhd and autism, also dyslexic. He works in the local rugby team as a kit manager and equipment. It doesn't pay well. He also prepares meals for his elderly grandmother and helps his bedbound uncle when he has the time. After years of being a SAHM i only recently started working in a school as a midday supervisor in a local school. It's low wage salary but it's better than nothing. Our marriage has had more downs than ups recently because my husband is a workaholic. He chooses to work on his days off than be with his own wife and daughter. We hardly spend time together as husband and wife and when he is home he is mostly browsing on his phone in the living room. I make suggestions but he turns them down. But an opportunity in work arises he's up for it and will often spend all day there or overnight. He's more like a roommate than a husband as I cannot remember the last time we actually slept together. I feel so alone in my marriage and bringing my daughter up on my own with no help from family. I don't have many friends and isolated at home. He went on this American tour with the rugby team as it was part of the 150th anniversary celebrations. It was all he ever bragged about while I had nothing to look forward to. He contacted me mostly every day when he was away despite the time difference. And I'm thinking why can't he be like that at home. It makes no sense. Anyway he was meant to be home on Wednesday but the airline forgot to place his team kitbag on the flight he was on. So he decided to stay in the airport till he retrieved his kitbag. The next day, he got his kitbag and was waiting to get a private bus paid for by the airline to come home. I had no messages or phone calls to say that he was on his way home. He kept ignoring my messages until I told him I had my first wage from my job. No good morning how are you just a text to ask me to send him half the money for bills. I refused because of the way he been treating me and his daughter. Plus I need money to live on. As he usually leaves me with little money to live on whenever he is away for work. And then he was surprised at how much little I earned. His comment made me feel ashamed for taking a low wage job. He went on ignoring my messages and calls. I was asking where he was he said he was out but no clues as to what he was doing or when was he coming home. Just said he will be home when he says he will be home. I got upset because even his daughter is asking and he's not given us a straight answer. Last time I heard from him was last night to say he needs time to think of what he has done to me and our daughter. And that he will try to come home. I feel so alone and lost don't know what to do for the best.
