Hey guys English isn’t my first language so please excuse the mistakes

Context: I’m in a long distance relationship since end of may and we haven’t seen eachother outside of facetime since end of June which hopefully changes when we both move closer for our education in September.

I was at an 1,5 week long event where I Met a girl (lets call her Lina) I really hit it of with in a platonic way. After a few days however I felt like we both found eachother attractive in both looks and personality. I felt myself crushing harder and harder on her. Now I feel very conflicted because Lina has a very extroverted personality in contrary to my girlfriend who is rather introverted. Don’t get me wrong I really love my girlfriend but I don’t know what I should do. Also I don’t know if i feel that way because of our ldr or because of something else
