If you have been seeing this girl for a few months how to tell her you have feelings for her so that you do not mess up the friendship or the good thing you have with them. How to tell them you like them so that if they do not feel the same you can keep on seeing them they way it is at the moment?
You tell them, and then it either works or it doesn't. Waiting will just cause you to lose your chance. Just go right out and do it.. Because like I said, it's either going to work or it won't.
Even if you can't comprehend being honest to her, you have to be honest to yourself. Talk about your feelings. She'll appeciate your honesty even if she doesn't feel the same way. Plus it's a good chance to take, she may feel the same way. Good luck.
I've always just said it and let the chips fall where they may -- I'm one who feels a strong compulsion to tell the people I love that I love them. Think about it this way: If this girl's feelings are not going the same direction yours are, how are you going to feel in another few months when your feelings are intense and she's still just hanging out being friends? Very unwittingly, I was friends for more than ten years with a woman who was desperately in love with me. I didn't know until after she went incommunicado how she felt, and she wasn't one I could have found romantic feelings for -- she was a rigid person trying her best to be a free spirit, and hiding low self esteem behind a nearly transparent facade. It was a particularly volatile combination and when she got overwhelmed by her emotions all hell broke loose leaving people wondering what they'd done to deserve such fury. She occasionally made sexual advances which I gently turned away, thinking because they always followed the end of some other relationship she'd been in that she was just rebounding and seeking comfort and I didn't want to ruin our friendship. She kept her feelings hidden at all other times, and even gave the use of her house for my second wedding and helped to plan the event. When she went incommunicado I assumed something traumatic had happened to her, and finally one of her closest friends clued me in. I felt like shit about it. It wasn't my fault, but had I known of her feelings I could have ended our friendship kindly out of love for a dear friend. By hiding her feelings she made herself miserable for a decade, and made me feel very badly, too. Now my otherwise fond memories of the good times we shared are forever tarnished, and I assume that she feels essentially the same way. I recommend finding a neutral place where neither of you are left stranded if the other bolts, away from other companions, and expressing yourself honestly. If it turns out she feels the same way you get to move to the next level as soon as it's said, and if she doesn't you spare yourself a load of heartache. There's no downside.
What are you hoping to get out of it? She doesn't know if she has feelings for you. If she sees in you some semblance of a celebrity she's seen on tv and whose power she admires, she might feel something for you. But so what? It doesn't mean anything. That's why I skip this part and make a move as soon as possible.
