what now?

this time 2 years back i fell crazy in love with his girl and our relationship was actually special for me cuz it was my first love. the first 2 months were all rainbows and roses but then suddenly she stopped replying and started leaving me on seen. i figured out thay she was studying crazy for her exams and waited patiently for them to end so we could get back at it (another 2 months). but it didnt go as i thought it would. she would still reply me once or twice a week n shit which lowkey pmo. i tried talking to her but nothing changed. i had to beg for her attention the whole time and tbh i was not in a good state. a whole year later, i decided to break up. now i think i have moved on, but what now? what am i supposed to do now?
