Hmm, I see no issues from your explanation. The girl should have listened to your explanation have.
This was exactly what I expected from her but I guess she was just not understanding.
Well things like this happens but it is not your fault and there is absolutely nothing to feel regret over. She didn't want to commit so why do you still take responsibility for her actions.
Let's just say I'm this kind of guy with a good and soft heart that doesn't love hurting people 😄
My candid opinion is for you to see such as a bad experiment and let it go as it is stopping you from believing in yourself when it comes to relationships.
Hmm... You're actually right about this and come to think of it, i began to see ladies as the same entity making me have a belief that ladies are all the same just like Juice Wrld once said "All Girls Are The Smae"
Thanks for your lovely comment with love from
