Uh - Wii - Josh and I have NEVER lived in the same city unless you count us owning our house together now.
When we began dating - we were living 1.5 hours apart. It never stopped us from spending every weekend and our vacations together. Not once. Now he is in Toronto and I am in Muskoka - 2.5 hours apart (app).
Prior to meeting Josh, I dated someone from Orlando. Nearly a 3 hour plane ride away. I was sure he was "The One". LOL When that ended - I swore that 45 min away was my max so wasn't so sure about getting involved with Josh at first. Just look at what I would have missed.
Consider this - space is good. You are still actively parenting. Not seeing someone every day makes seeing them even better. And your daughters' will still get the time from you that they need.
Speaking of your daughters - how are things going? You haven't mentioned them much lately.
