ok just stop messaging her first... and see if she messages you... if she doesnt within the first day... then dont be sad... if you've done everything right she'll message you within the first week of you not messaging her first...
i too have a girl that im getting with now that is similar to yours however mine is in person and not the internet lol... i was always the one that would message first and was getting a shit load of IOI's... but she'd never be the first to message me... i ran my "i hate needy girl" routine and i think thats why she didnt message me first... but then i started showing her a lot of IOI's in person and she responded really well and then started messaging me first if i didnt... some girls are so used to getting attention from men that they dont even bother trying to get the mans attention... so... i suggest you meet up with her as soon as you can otherwise all this attraction will be gone and you'll have nothing... plus online gaming is only good for about 3 days... then you need to meet up to gain a physical and emotional connection
fuck knows if that'll help you but whatever
