@ astraalyns Lovely Astra I may not know you but as a Muslim who is straight, my view will not change about you. I accept you still as a person and I hope you will move out of the toxicity in your household. LGBTQIA+ topic in Islam is okay to talk about, it isn't taboo at all.
I wish you well a lot of health from your heartbreak and it must be horrible of this especially finding out about your friend that she has a crush on a guy.
From what you wrote and said, you aren't a bad person, you're a person who is living in a toxic household and have a best friend you love that has feelings for someone else.
Jealousy is a normal yet negative feeling we all feel and at the end of the day, no matter how jealous you feel, it doesn't make you a bad person as long as you don't harm her mentally nor physically or even verbally.
It also didn't sound like forcing to me, you are just very hurt and living under difficult circumstances.
You deserve to be cared, loved and a lot of acceptance that you cannot control mentally and emotionally what you feel and you deserve better people than your own family and so does your best friend's parents.
I hope you both will gain hope someday even acceptance, understanding and love.
It doesn't change how I view about you Astra, even if we don't talk a lot.
I still wish you a lot of care
