Between a rock and a hard place.

Since i started highschool ive met tonnes of new people because only 3 people from my primary school goes to my new school. I only keep intouch with about 4/5 old friends but especially my friemd monique, Shes the best thing in my life, but i also have a best friend jess from my new school.

they both get along but i seem to be spending more time with jess and to be honest its not that i like her better but shes more like me she understands more,

i feel really bad, is there anything i can do?
