empowerment over, just had H pack his bags

[canadianMrs.]

Its been a while since I've been here. August, I moved to my new house in my home town. I've been busy settling the kids and myself up in our new lives, and have been busy seeing family and friends. GAL has been very easy. Kids have had a few rough spots, but are doing amazing considering. A few friends of mine work at their new school, and that has been a huge help. Just started looking into a new career for myself...after 10 years!
The thing is, ever since the move H has been coming to see us ever other day. Its almost a 2 hour drive. We have become friends. We have done things as a family. On his weekends where the kids activities haven't allowed for him to take them to his house( now tiny apartment!), he's stayed at my house with them, and I've stayed with my sister or mom. I will admit, people think its unusual, but it seemed to help the kids and it seemed to help me heal from this.
I've been doing this with DB in mind, although not 100% sure I wanted to get back together. We were leaning that way for a bit, but then went back to not talking about it, and just be friends. I told him at the time that was all I could commit to for now. He has helped me alot with the kids and the move etc. I like the person he is trying to be, but I still have a hard time with what he has done, and some of the MLC stuff that pops up from time to time. You can see there is still a battle going on in him to do the right thing vs MLC. A lot of talk/crying about how hard this is all on him...what about me/kids? He did this! This is what a year ago he wanted!
Anyway, my big issue right now is that I feel a shift. I'm detaching naturally, with no thought to it. The need for him just isn't there anymore. The more I'm around my friends and family/GAL the more I think he's not right for me. I'm not sure I want to stay this close anymore, and want to put some boundaries up.No more using my house to stay at etc. How do I do this. Do I talk to him about these feelings or just start implementing new things.
I hope everyone here has success in DBing over the last few months, whatever that is for each person.
