stressed & pulling away

so i have been talking to this guy for a while now *about two months* and we talked pretty much everyday, but only hung out once *met on tinder* and have both been super busy ever since. we were talking about hanging out again recently and we were both super excited, but about a week ago he has been placed under a lot of stress and has completely stopped talking to me. i know deep down that it isn’t me for being the reason he has backed away because the days of everything happening he was still texting me first and was very apologetic about not answering on of my texts the day before, i guess this is all very hard for me because i don’t know what has happened to make him back away because he hasn’t talked to me since.. has anyone experienced something similar to this and have any advice?
