Ex is leaving in 50 days, and i fucked up NC. What to do now????

My ex was a foreigner and he came to my university for a 5 months study abroad course. We dated after 3 weeks of getting to know eachother and break up after 1,5 month dating.

When we first argued, he demanded for a week of personal space and time for us to think, but i told him that i wanted to break up. We didn’t talk anymore. But 1 week later i couldn’t stand and talked to him first and said i wanted to get back together. He said he thought it was better for us to be seperated, but still he thought about it for another week and decided to break up.

Just after 3 days, i texted him and asked him out, he went out but said we’re only friends. I told him i still wanted to get back together and he told me its already over – we are never getting back together. He will only stay in my country for almost 2 months and he doesn’t want to spend his time with me anymore, nor wanting me in his life.

I still love him, so much. Should i do NC for a month? We already had 2 weeks of staying silent and another week of me chasing him. If it works, we can only be together for 1 month only.
