Self Struggle

I am so struggling with what decision I need to make. Do I go back to Ohio where my kids are or do I stay in Florida and work my butt off to get my kids here? Ohio doesnt make me happy. The winters there just kill my body anymore. Florida makes me happy but my kids are not here with me yet. This isnt how it was supposed to work out. I left a very good paying job(in THIS economy) left my house that I am paying on in Ohio to move down to Florida. I moved here with the idea that things were going to work for me and my bf, we found a house big enough for me, my 2 kids and him. After about 3 weeks of living together we both realized that we could not live with each other, it was not a very good thing. We are much better when we are not together all the time. So now I am at another fork in the road, do I stay in Florida or just go back to Ohio? Part of me wants to go back to Ohio(for my kids only) but I know that I will not be happy in Ohio anymore. Part of me wants to stay in Florida and work at getting my kids down here with me but that is going to take time to accomplish. My life is never easy. I just really dont know what to do. I wish I had a crystal ball and could see the future it would be so much easier. If we are talking about wishing, I wish I would just win the lottery already and then everything I want to happen in my life can. Wishful thinking, just as I said before my life has never been easy like that.
