@Cookie Be calm and don't ask her out in situation when it may be uncomfortable for her or for you- avoid asking in other people's presence. If you're friends, I assume your conversations have casual manner, so try to keep it that way. Make sure she knows it wouldn't be a big deal if she said no. Good luck.
@Cookie it's easier because you know eachother, just sit her down and have a one on one and tell her you have feelings for her and say it won't change the friendship if she says no but she would probably feel awkward
@Cookie And should she say no, don't lash out your furstration/deception on her -- nor be jealous once she go out with some good guy/girl.
Last pieces of advice : don't get your hopes high, don't be/act like famished dog, don't be impatient nor egoist (=be mature) and choose the right TPO for both of you to be at ease yet enjoying the moment -- might sounds weird but not all rejections or breakups taste bitter nor be bad memories 😉
(I've had a colleague who even threw an anniversary party with her ex husband a year after the divorce, both of them having found new partners and still complice (=strong agreement and trust) on how to raise the kids they had before divorce. The young son even pouted because he was twice more "surveilled" -- since step-parents had the right to scold him the same way as his (blood-) parents 😂)
@Cookie honestly if you are seen as a brother/friend as the first impression then it might be hard to be seen as a romantic intrest but who knows you might have a chance
@sky tbh I don't even know what am I seen as cause there was a time last year when she used to call me baby in Spanish and know that I think ab it usually friends don't do this.. right?? She's the type of person that u would never find out what does she think ab u cause she's shy and doesn't really talk ab her emotions
