So basically part 3 of the Ethan story. I decided to wait for him to get better and for him to text me first. I waited and waited and waited for him to text me to no avail. I texted him today abt this school contest so that he votes for this specific group. He replied the first few times but my last message got ignored. I honestly think he's sick of me and tbh I miss the chemistry we had at the beginning. I feel kind of numb now, kinda like I'm over him but I'm not. I really hope he didn't lose feelings. Should I just let it go and move on with my life?
