@lumimagin sounds toxic, maybe if he gains her trust, they might be cool.
But she can't love him if she don't trust him. She might just infatuated orelse have a crush on him. Trusting each other is THE MOST IMPORTANT thing in a relationship.
She should just have a break n see if he's that imp in her life. Like if she's still happy n peace without him, and he doesn't take any step to make the relationship work, yeahh you got the answer.
