I am kind of going through same issue as you’re. But in my case..family is pressuring me to just settle down no matter who that is. But thing about me is that..i am firm to them (not disrespectful). But just firm that..i cannot just settle down with a girl like that. Without even knowing her and have attracting with a girl. But i have learnt a lot from your thread.
And as per your thread dude..i say let her be. It is just 7 months. I hope and pray to Allah that.. Allah gives her and you happiness going separate ways. Because you do not want to live a life of misery. I would rather live single than go through a misery in life like this.
