ADVICE NEEDED ?

So let me start off by saying. This guy and I have known each other since middle school through high school. We lost contact for like 6 years and then we started speaking again. Fast forward we are texting and calling every day. After like a couple months we go on a date. It was sunshine and rainbows. The best date i’d been on. I felt so comfortable and happy and he felt the same. See, we are usually very open with how we feel for one another. Everything was going well. We were still talking everyday texting and calling way after the date. Then all of a sudden I don’t hear anything from him. I’ve called a lot and texted as well and it’s been radio silence. I created his bio for him on Instagram awhile back and he hasn’t changed it. I don’t know what’s going on. I thought everything was going well, there were no signs that it wasn’t. He’s told me that he goes through tough mental days sometimes, so it could be that but I haven’t heard from him in a month. What is happening? What should I do?
