"He's been asking her to sit down with him properly, have a heart to heart – but she's refusing.
"She wants to keep things civil for True's sake, but she doesn't want to risk falling for him again and getting her heart broken all over again.
"He's really keen to show her he's changed, though – he's even buying a big 'family' house near Khloé's LA home so he can have True to stay more often, and saying he'd do anything to put things right. Khloé's torn."
Last week, Khloe celebrated her 35th birthday and received a tribute on Instagram from Tristan, in which he described her as "the most beautiful human" he's ever met.
He wrote: "Happy birthday @khloekardashian You are the most beautiful human I have ever met inside and out. Thank you for being an amazing mommy to our princess True. She is blessed to have someone like you to look up to. I wish you nothing but more success and sending you positive blessing your way. Enjoy your day Koko (sic)"
And there's a chance a reunion could happen, as the 'Revenge Body' star recently said she isn't dating yet.
She said: "I'm not dating right now. But I'm enjoying [life]. I love life. I'm just really enjoying my life and my time with my baby and family."
