You’re gonna have to get some normie hobbies first before anything otherwise im conversation you won’t be able to relate to her at all.
Imo flirting is no different to messing around with a friend. Obviously make it known you have an interest in her from the way you look at her and all but guys make the mistake of thinking “I need to constantly compliment her, I need to always say something good about her; ask her about this and that” When really you can say whatever the fuck, good or bad. It’s about how you make her feel when she’s talking to you.
Say what’s on your mind and talk you’re in a normal convo, tease her, genuinely compliment her if she deserves it. Not just because she exists
Watching videos on this will just make things seem forced
If you’re having fun in the convo, not trying to suck up to her in any way, there’s a likely chance she’ll try to match your vibe too. There’s probably plenty of men who have tried the obvious lovebombing strat on her. If not and she’s signalling not interested well oof
Mb if this doesn’t make sense, it was hard to put it into words. You just get better at it the more you practice
