Micha asked 1 year ago

Hi! My long distance boyfriend hasn’t responded to my text in 4 days. He’s been known to shut down if he is under a lot of stress. He did that once couple of weeks ago and said he still wants me to be his girlfriend and it had nothing to do with me.
four days ago, he made a comment that this week and next week will be very hard( assuming with work) so I asked him why? And then silence for 4 days. 
I haven’t reached out cos I wanted him to have space. But now I am getting really scared..
what should I do? 
Thank you!!
