Loving a taken woman?

I don’t know what I’m doing on fluther honestly, I found this website about 4 minutes ago and decided to take a leap and ask someone. About 4 months ago I met this amazing girl, she’s without doubt the single most perfect creature on this planet. We had first met with some friends but I was to scared to talk to her and I normally I have no problem talking to girls only one other girl has ever been able to do these things to me and I that was just a grade school crush.

I finally got the balls to talk to this girl and quickly it turned into a great friendship, little did I know I was falling in love with this girl. From just about the start I’ve known she has had a boyfriend. We grew closer and closer as time went by, now I’m the 2nd most important person in her life and shes my most important. We talk everyday with each other for hours a day about everything and nothing.

She is a culmination of everything I ever dreamed of finding in a girl and stuff I didn’t even think I wanted. If I ever find an imperfection in her its hastily washed away and replaced by a view of beauty about the subject matter. I try and try to find things wrong with her so that maybe I can love her less but it just strengthens what I feel. I can’t even remember what the imperfection were, it’s like they have been wiped from my memory completely.

I’ve become a confidant of sorts for her. I just want to be as close as I possibly can to this girl. Every time I make her smile or laugh it makes me so incredibly happy inside I just want to feel like that all the time. She’s told me things about her relationship and how its quite shaky, the guy is quite sketchy and has a lot of abusive husband type traits which really gets under my skin cause there’s nothing more I hate than abuse against women, I’ve helped a lot of friends and a few family members through abusive relationships.

She’s practically cheating on her boyfriend with me but I’m so new to these feelings I’m unsure of what to do, think, say, anything/everything!

I’ve told this girl I will never leave her no matter what I’m sticking with her till the end. Before meeting this girl I was quite broken, unhappy, and depressed. I continuously sabotaged relationships not with just girlfriends but with anyone that got to close with me. With her though I’ve completely let her in and I see no end to our relationship ever. But since being with her I’ve wanted to actually live, be with people, go out and have fun.

One last thing, this is a long distance relationship, both I and her and her and her boyfriend.

I’m not really sure what I planned on getting from typing out all this but I guess I should probably get to my question. Firstly am I stupid for being in love with a woman who loves someone else more than she does me? And secondly should I bother waiting around for her relationship to end, I so badly want to be with this girl in a more meaningful way that it hurts. When I see a couple out my heart aches and immediately thinks of her, I want her more than anything I’ve ever wanted before she’s like my air I can finally live when I have her in my heart. I do feel I’m being foolish loving someone who has told me she loves her boyfriend than she does me. Please help me ;-;
