Long story short. We were a thing for almost 2 years. Never made it oficial but acted as if it was. Things went south due to his lack of time and effort and i called a break. Almost two months pass i felt like i was ready to work things out and reached out to him. Things went alright, we started talking again all the time but more friendly than anything else and it seemed like we were both comfortable with that. I told him I had to tell him something (apologise for wanting space and leaving) but he never brought it up so i guess he was avoiding it and i didn't want to pressure him. That was a month ago and things remained the same with constant communication. Well from a few days back to the present he's been very distant. He's taking hours to reply, and today, i haven't heard from him the whole day even when i texted him this morning. What should i do?
