I'm an 18-year-old guy struggling with something that's been bugging me for a while. Whenever I find myself liking a girl or notice a girl showing interest in me, I tend to avoid them or shy away from talking to them. It's not that I'm shy in general... I have no problem chatting and having fun with girls that I don't have any feelings for or when i notice that they don't seem interested in me.

For example, this summer, I noticed a girl around my age at the pool who was clearly kinda interested in me. She went out of her way to make it obvious, like waiting alone for me, making eye contact, and getting embarrassed when I looked back. At one point, she and her little sister were in the pool, and when her sister said hi to me, I said hi back. The girl blushed and suffocated her sister out of embarrassment. Despite all these clear signs and finding her attractive, I couldn't bring myself to do anything more than just say hi and walk away very fast... It's like the words just wouldn't come out.

This has become a real problem over the years, and I’m not sure how to overcome it. Also, I should mention that i'm not unattractive as i have been told that by a girl. I also did try to improve confidence by going to the gym and having a skincare routine etc. But that didn't help me with the ongoing problem. Any advice or tips on how to help me would be appreaciated or u can just make fun of me instead.
