Should I leave my husband?

I actually love my husband very much but at the same time I hate him. We have three children together and have been married 8 years (together 15 years). He never listens to me - it is like I am not allowed an opinion - I am not a soft touch and I do express my opinion but I know when I do it will result in an argument rather than him seeing my concern so half the time I dont say anything. I dont feel this is right - I should be able to say I disagree with him without him sulking. If I speak up then there can be silent treatment for days which ALWAYS results in me being the one to try and console the situation. The kids dont like us arguing - again what is better - them hearing us arguing (it is not physical but very verbal) or we split up and them having one parent when I know how much they love their dad. I have spoken to my husband many times about how his temper scares me and the kids, he appears to understand/be apologetic then we are back in the same situation. Money is a big issue as he is out of work since last year but again, everybody is trying to help him find work but he is constantly coming up with excuses as to why he cant do or its not suitable. There is so much more but I dont know what to say/do - really I am completely lost. We lived in Australia for 10 years &he wanted to leave- I didnt but I did because he wanted to- now he wants to go back after 5 years but I dont want to with 3 kids leaving grandparents, support etc yet he is making me feel guilty for my reasons. I can give him what he wants and we have an easy life or I stand up for what I believe and life is uncomfortable!! Please help!!
