I think im cooked

Me 21 (m) met this girl now for twice. First time we were on a walk and the other time we were playing tennis together and after that went on a walk again. Im very inexperienced and shy and I dont know how to initiate touch. And i dont wanna come up as creepy or make her feel uncomfortable. Before meeting we were talking for few months because she was living in different country but came back a week ago.

I have had great time with her and shes always laughing etc. (I think thats a good sign) But I dont know if shes actually feeling me at all or is she hanging out with me only because of boredom.

I overthink everything and im feeling like if dont do anything she starts to think me as a friend only (or if she does already lol).

I have read many reddit posts about similar problems but I dont know what to do.

This shit is making me crazy. Please help😭
