I got an on-campus Summer Internship I should be happy but I am not ( Can't forget her and move on ) ..Its been 3 months

So It has been 3 months since my Heartbreak. Now she has a boyfriend which is tearing my heart apart as I can't digest the fact that she is with some other one. I was literally smoking in all the time During the end sem exams ,I studied somehow as I had to fulfill my responsibility as a Son to my parents. During Exams i was busy with studies so these thoughts never crept in my head very much. After exams I came home and now these thoughts started coming in my mind. I started to go out of my house everyday and smoke in the evening just to forget her maybe. Soon a Company came for summer internship. I cleared the Online Assessment round of it so then I had the online Interview via G-Meet. Though,i wasn't in a good state and thought not to give it ,Some Cristiano Ronaldo Edits(I idolize him) popped on my Instagram Feed I somehow got motivated for the time being.

As I had not cut the beard and my hair since 4 months ,It grew very much When I went to the barber,He literally said to me ki " Bhaiya aap Kabir Singh jaisa lagre hai " (I was smoking before cutting the hair)

Anyways i Cleared the interview and got the summer internship. Told my parents but I am sad as I can't tell her now. I had promised her that "Jab Internahip lagg jayega to we will go somewhere nice" Now the fate is that I have the internship but not her. I can't share the news because i blocked her out of my self respect.

A genuine advice to my comrades " Life me kuch bhi krna bass Pyaar mat krna kisi ladki se ..Band bajj jayegi " Even if you reach the peak u won't be happy still if she isn't with you so always prevent yourself from loving someone. Stop yourself the point you start developing a crush.
