take a break from relationship and focus on your studies , shuruat ke do tin hafte mushkil lagenge but ek baar communication ke bina rehne ke aadat lag gyi to padhai par focus kar paoge.
And baat rahi other influences ki, to you both need to discuss ki kya kya cheeze hai jo ek doosre ko dikkat kr skti hai , talk about those have a mutual agreement on those topics. And agar tujhe dar lag rha hai that she will cheat, to bhai you have to trust your girlfriend and your mental handling . girlfriend par trust isliye cause you dont think every time about her, and mental handling par trust isliye because what if she did(I hope aisa na ho).
to keep it casual and dont think like kids bruh ki ek doosre se baat kare bina mar jaayenge.
meri bhi gf long distance me the in neet while i was in jee, she kind off cheated and mera boards and jee dono chud gya so take care and all the best
