<human>: Dated a girl for 6 years exclusively. Broke up for a variety of reasons, none of which were baleful, and the separation was mutual. Of course, being together for 6 years, we're best friends; I can talk to her about anything and the conversation flows perfectly.

She moved to the opposite side of the country post-breakup. I live in LA, where finding friends is...difficult. LA is a very lonely city, beyond superficial interactions, and it always has been. She moved to where she doesnt know anyone, in Pennsylvania.

So we're both lonely. We both try to keep busy and to focus our energy elsewhere, but we're both lonely and both still in love with each other. Occasionally I'll go home for family reasons to Ohio, and she'll make the commute to meet me. We'll hang out and have fun and have sex - the friendship/sex combination has been a part of our relationship since before we started dating, a sort of 'im hot, youre hot, lets fuck' situation.

Everything's been good. I've visited home a few times, and we've been good at compartmentalizing our physical flings away from our friendship, but something came up last week; I mentioned our traditional sexual encounter, and she replied with 'I dont want to if you're seeing someone else' which is a perfectly valid and respectable stance. But has raised some conflict.

At which point do I stop giving deference to her? She is my best friend, and probably the best lay of my life. She will get upset if I refuse her sex, as that constitutes admission that I'm seeing someone else, and will damage the friendship that I value so highly because LA is a smoking wasteland where meaningful interactions go to die. But I also recognize it's highly manipulative - she knows I value the friendship. And she knows by taking this stance, she is manipulating my behavior, because we're still in love with each other.

Because we're friends, we still talk pretty often - at least once a week.

Can you succinctly summarize the text in 1-3 sentences?
<bot>: Still in love with ex, ex still in love with me, wanted to maintain friendship, but our sexual independence from one another is making a mess of things
