Thing is, I don’t think his music is his number one priority. He’s not done any promo for it, he’s not even in the country for any of its release. He wants to be in LA, that’s where his life is and I think if Emily lived in LA from day one they’d be living together and fine. Like how he was with Gabby for years in NYC, they did everything together!
He’s lived in LA for years and only came back for promo and tours with the bands, he was doing this with Portia as well, in fact he left to live in LA while they were together. He probably never lay all the cards out on the table or she was too caught up in him being “famous” to realise it will never be a real grown up relationship.
The kindest thing he could for her is to let her go and she needs to find someone who will support her and help her - she needs just a normal lad away from YouTube etc who will bring her back down to Earth.
