This boy

I am a 14 year old girl and I recently have became interested in this boy and I guess he thought I was playing “hard to get”. We talk good through text but when it comes to speaking in person it becomes awkward and his friends decide to place them selves into the situation and then every time I pass call me names. Today he messaged me asking why I was fussing because he didn’t shout me and I responded saying “I wasn’t, I’m so confused”. After a back and forth argument it’s clear to see that he’s not interested and it’s acting like the little boy he is. My problem is I can not tolerate the disrespect which he and his friends show towards me and at this point I see everyone getting into relationships and yet I struggle to talk to boys face to face and have a proper conversation as I find my self to be shy. Do you guys have any tips on how to improve this and be able to shoot your own shot
