Want to Separate, but conflicted

I have been married for almost 6 years to my husband, whom I met about 8 years ago. We have a 3 year old son. For the past 2 years I have been unhappy. I have had conversations and emails with my H about this several times, but nothing changes. He went straight from his parents to me and I feel like he has never grown up. He is also 4 years younger than me and we met right when he turned 21, which I feel contributes to the issues we have. Essentially, I feel overwhelmed because I do everything. I worry about our bills, I take care of our son, I clean the house, cook the food, do the laundry. And this makes me feel like he is just a burden. Additionally, we are not intimate. We never really have been. Even on our honeymoon we only had sex once. (sorry if that is an overshare) I am done being un-happy with my life. My son has seen me break down and cry hysterically because I am so unhappy and I dont want him to think of me that way. I have been thinking that we need to separate, though I think I am really thinking that is just a gateway to divorce. I have spoken with friends about this. I have spoken with my parents. I am just worried about how this conversation will go with my H. Would like any advice on my situation and how this conversation might go!
