I will give you an example of this. I talked to a girl this weekend who also is in the same school as me. Yesterday i talked with her in the train and it was really a amazing conversation. She stared at me the whole ride. Laughed about everything that i said. She touched me multiple times for no reason. Touched my thigh, leg a few times and asked me personal questions so i think she is kinda into me. But yesterday someone told me that a guy i know who is also in the same school hanged out a couple of times with her. And today i saw her talking with this guy again. And it’s always gets me in a mindset of “fuck this shit” and i get frustrated and just don’t talk to the girl anymore even if there maybe is a chance of getting her if i just persuaded her. I have had this many times. And i missed so much chances with this. I just can’t be the fun guy (that i was when i first talked to her) when i finds al this things out.

Edit:

Thanks people on Reddit! I was in a similar situation last night. The girl even had kissed someone else before. But i just did my own thing and ignored the other guy and she was the whole night with me and we ended up kissing. She texted me how much better i was then the other guy and she regretted kissing with the other guy.
