<human>: Can you give me the gist of the text in a nutshell?

To cut a long and painful story short:

Guy is friend with girl for 6/7 years. Lots of laughs, it never goes anywhere due to guy being coward/wrong place/wrong time.

A few weeks ago. Girl is in long term relationship with other guy (Rick). Meet up on holiday. (She lives in another country, about an hours flight) She admits she wants to be together. Guy is very very happy.

A week ago: Girl says she's in too deep with current guy. Can't start again. Guy is sad. Guy says he needs space. Can't talk as much anymore.

A few days ago: Girl gets drunk, is upset. Wants to talk with guy all the time. Wants to be in relationship again. Guy happy again.

The day after: In too deep, loves Rick, he's moving over. Guy is very fucking depressed. Guy can't talk to her anymore. 

Today: Message from girl saying how she knows we're not supposed to be talking gets to be home for Christmas for the first time in years. I haven't responded yet.

I love talking to her, she's one of my best friends. I don't want to lose her, but I can't sleep at night anymore with these awful thoughts of missed opportunities. It's turning me into a depressed zombie. But the idea of talking with her made me kind of happy.

Do I cave and start the conversation again or do I just leave it?
<bot>: Almost get together with friend of 6 years. She backs out. Do I try to save the relationship by just burying the feelings?
