Friend disappeared for months, should we keep texting him or is it a sign he doesn’t want to be bothered? (Problems at home and we suspect depressed)?

We haven’t seen him for almost 6 months now and he almost never texts back, to none of us. The last times we saw him he looked anxious and distracted/worried. Two of his siblings got tangled up in a religious cult and went through burn out last year, that was worrying him quite a lot back then. However, we know that he is still working (a lot) and also hanging out with his work colleagues, he still appears on their insta pictures at parties and dinners… so he hasn’t given up social life completely, we don’t understand if he just doesn’t want any more of us (there were never tensions/fights/discussions…) or if he is struggling and we should keep texting him to show support…
