I broke up with my boyfriend a week ago, he was too busy with work and he've been acting stone cold for like 2 month,,, when i asked why? he told me he has a lot too do, so busy, too much concerns then told me he can not be responsible for a romantic relationship anymore and if i want to keep this relationship there wouldn't be any emotions. Then he broke up with me cause he saw I'm so sad and i can not take it. But after 2days he texted me then we have a video call like before. It made me so happy he changed his decision. But a day after he was gone... And he didn't reply my message anymore... Why is this happening?
