Lonely and torn

My husband, youngest daughter and I moved from our home state 2 years ago leaving behind all our family, at the time we were all happy for the move, our eldest daughter decided to stay in home state for her job, hardest thing I have ever done but we were too far into the move to not go. At the time my husband told me he had been offered a new role within his company but I later overheard a conversation he was having that he had asked his boss for the move.
My husbands life passion is sailing yachts and due to his brother having a yacht and lived in the new state, this was his reason for the move.
Now sailing has taken over his life, most weekends, time away throughout the year also and more plans for longer stints away.
My daughter who lives with us is working more now, so I spend a lot of time alone.
I feel like I’ve lost my identity, I have no interests, no friends and no family around to spend time with, I go to work for 10 hours a day and nothing else. I get angry and jealous at him for the time he is away. I can’t stand that there are women as part of the crew, always imagining him leaving me for someone who has the same interests, my jealousy eats away at me all the time. I hate it when he talks about it, I hate it when his phone is constantly going off with boat chit chat. I have tried to get involved with it but I don’t have the sea legs nor the love for it he does. how do I find me, how do I find my thing?
I have thought of packing up and moving home to my other daughter who I miss desperately, my youngest would be happy to go to, easy job move for me but not my hubby, I don’t think he would go back and if he did he certainly wouldn’t be happy, this lifestyle suits him. Do I give up 24 years of marriage and a husband I love to find my happiness? Is that selfish? How do I find myself, I just feel like crying all of the time!
