Divorce..

So, after a lot of back and forth I have finally decided that I want a divorce from my husband. He's not taking it so well but I just can't keep going through the same things over and over. It's exhausting and we've grown apart to the point where we just want different things. Some of the things we want are still the same: family life, a good life, to be stable. But I just felt myself growing more distant and unhappy. We've been together 5 years and married 2. He keeps telling me I'm breaking up our family (2 boys) etc. I told him if he would've made the changes I asked for in the first place we wouldn't be here. I'm a little sad about it but mostly scared because I've never been on my own. Anyone else ever been through this? I'm sure there's a lot of you, I just want some advice.
