You sound very personal involved in there lives lmao. Take a step back sis.
Personally, I could never stand Selena. She's amazing at playing the victim and always getting the public to play in to her 'woe is me' act. This is her 4th time singing about this break up and discussing Justin then proclaiming she is an independent, self loving woman who don't need no man when she has her BFF's lol - Then we see her hanging off Justin again. No respect for herself, her image or any of the people in her life who Im sure tell her to break off and move on. Selena would've made a habit of going back, breaking up, going back etc if it weren't for Justin moving on in the end. She can like all the hateful comments she wants, but both her and Justin are as toxic as each other. She has a drug and alcohol problem which he has alluded to in one of his songs re the break up over 4 years ago (YES, its been that long and she's still going on and on).
Hailey is another issue and although I think she does have some issues of her own. She is no messy Selena. She may be obsessed with Justin but clearly he's someone who needs that kind of love and reassurance that someone will be there for him (maybe from his own abandonment issues) - Don't even get me started on that cult like church they all go too, major creepy vibes. I don't think their marriage will last but Justin seems determined to have kids and prove he can be a better dad than his was so maybe Hailey's dream of her own little Biebers will come true before they head for divorce. Having said that she did say she doesnt believe in divorce when her parents were on the brink and she was asked about it. All in all, its a mess.
I wish Justin would clean himself up when he leaves the house. Always looking homeless.
