Left alone / being bullied

I have been married for 2 years to a great guy, we are in love. We own our own business and it is very stressful we dont see each other enough. It's very rare that we share a meal together. My husband gets so involved with things not just for our business but for many of his friends. When we do spend time together he gets on his phone and talks to his buddies. If we go out I spend at least half of the time alone usually we are in local restaurants and he has to go talk to someone leaving me. I started to think maybe he really does not want to be with me, I confronted him with this and he could not believe that I could feel that way, he said he alway wants to be with me that I could always go with him. One other thing that is really bothering me is we go out on our boat now and then and when we do it is like I am under the microscope He has been boating most of his life I for about 3 years Every thing I do is wrong I try very hard to think ahead and do everything properly this usually consists of tying up the boat when we get to the docks. He gets very irritated and says things like how many times have I told you, you have done this many times when usually what he is talking about I maybe have done one time before or he has done it without my help. This has made me on edge Im afraid each time we go out, something that should be fun is made stressful. I am very sad, stressed and dont understand. I dont know how much more I can take I have tried to tell him How I feel but I must not be communicating it very well. I need help!!
