I don’t know what to do

Recently I have been trying to get into a relationship and I have been chatting with a female friend for some advice on women and recently I have realised that I think I am falling for her. But there is one massive problem, she has a boyfriend. I don’t want to tell her as it may screw up her relationship with her boyfriend and I want her to be happy, but at the same time I want to tell her as I also want to be happy. Some advice would be great

Don't do it. You don't want to be that person who possibly breaks up a relationship, or confuses things for her and makes things messy. It could become very uncomfortable for her if you say something, and she may also withdraw from you. Just let her be with her boyfriend and go on dating other women. It's all you can do. Let it go....

If you can steal her away, she can be stolen away, from you too

Women aren’t a possession to be stolen

I never said they were. When in a loving relationship, each belongs to the other, no matter the gender(s).
I'll reword for you...
He probably doesn't want someone that would cheat with him, because he'd then have a cheater for a girlfriend.

When you say you've been talking to her about women . Do you mean advice on a particular woman , or just women in general ? If it's the later , then she is probably being quite open on what would impress a woman from her perspective . So it would be easy to feel a connection to someone who is being so open and honest with you . If that would translate into a meaningful relationship in the long run is up for debate . You'll have to decide what your going to do , but if she is already in a happy relationship then it doesn't sound like a good idea and could make her unhappy . Which seems unfair seeing she has been so kind . But your the only one who knows the full circumstances .
For myself , I worked out trying to cut a friends grass regarding their girlfriend isn't such a good idea when I was 16 . He confronted me about it and I was apparently talking when I should have been listening ...so him and his brother knocked a few of my teeth out to explain their feelings on the matter . We still laugh about that at reunions . Oh and p.s. , the young lady forged a career in the armed forces before marrying an airline pilot and having three lovely kids . So she was the winner ...and didn't lose any teeth in the process .
Think long and hard before meddling in relationships .

Thank you all so much when it comes to relationships I just suck, I would never want to hurt any of my friends especially someone within my close group of friends. Thanks again

Yeah, it is best not to say anything. I hope you can find someone who is available.

I hope so too

do you lack confidence Jason ? If so just imagine yourself at 95 looking back on your life . Remembering the opportunities you passed up because of some useless apologetic complex , what would be the advice to you from the 95 yr old you ? It's very cliche, but it's true that if you believe in yourself then the rest of the world buys it too. Doesn't matter what you look like , how much money you have , because being unashamedly yourself is the most attractive weapon you have .
What would I know , you might be the most confident person in the room . If so , apologies for my presumption .
. When I met my wife 30 years ago the standing joke has always been from her " she wasn't actually even sure that she liked me , she just wanted to stay around to see what crazy thing was going to happen next "
Perhaps living every day as your last day is a bit over the top , but living every day without fear is def not .
Find your own way.
