<human>: Can you provide a brief overview of the text?

Okay, I will try to make this as short as possible.

I have been with my boyfriend for a year now and I couldn't be happier with our relationship. I could go on and on about how absolutely amazing he is. I envisioned a life with him, marriage, kids, white picket fence, the whole shebang! 
Now here is where my dreams of a life together go to shit:
Last week he gets a call from an agent in LA saying that he got a role in a new indie movie and that he will be needed for filming in LA for the month of January but he should consider moving to LA to pursue acting full time. Now, this is not necessarily a new topic of discussion for us. In the past we have had this discussion several times, though the discussions were never serious or definitive, they were more of just ideas to him at the time and at that time we weren't super serious so it didn't really resonate with me. So when we talked last week about his decision to move to LA I was completely caught off guard. Needless to say, I was/am devastated. I feel like I am going to lose my best friend and the love of my life. Even though he has assured me numerous times that he loves me deeply and is 100% committed to making us work long distance (seeing as we would only be 5hrs away), I still am hurt and saddened by his decision to leave. I want to support and encourage him on his journey to pursue his passion; I have want to have him resent me or regret his decision to not go and pursue acting. At the same time its very hard for me to come to terms with. I would love to go with him but I have a 5yr daughter who needs me more and a good job I cant/don't want to leave. Any advice to help me to cope with a LDR is much appreciated.
