What Value Do I Bring to Your Life

I have been in a rather perplexing mood today. Have not been feeling my best. Trying to figure out still where I fit into my fiancee's life. I often want to ask him just what kind of value do I bring to his life? Where do I fit into his grand scheme of things. I would love to have some uninterrupted time with him, where there are no phones ringing and we are just enjoying each others company. I feel like I often have to take a back seat to other people in his life that mean more to him than I do. I just feel really neglected by him and it's making me wonder is this what I have to look forward to in being his wife. He says he doesn't want to take me around those rough characters he runs with and he knows I can't be out in the hot sun like that, he also said that it doesn't look good to have his woman around all those men, but to me I really wouldn't care as long as I was with him. There are times when I just want to quietly walk right out of my life and start over, but that's not going to solve the real issue for me and that's would his life be better off without me in it? I cry almost daily now because I feel wrong for wanting to asking him to put me first in his life. I feel sometimes I don't have a right to ask him for these things what do I do.
