Conflicted feelings

Hey everyone, sry for this but I guess I just need to write it down somewhere to get this off my mind.Basically, I am still hurt because my crush, Niko (someone I really was (and still am somehow) in love with) broke my heart a couple of months ago. The main reasons are that I wasn't his type and that he began to date another boy, let's call him Max, shortly after that. Before you ask, we weren't in a relationship, just "friends". I met Niko trough Grindr, and apparently Niko and Max also met trough that app. They began to date and I think for a couple of months. But I always had that inner feeling, that it won't work out between these two. Not because I wanted it so badly (I want Niko to be happy), but because something about them felt off. After confessing my feelings to Niko and talking about them, Niko and I did't have any contact for 4 months now. I always asked myself what would happen, if I just texted him, and yesterday was one of those lonely nights, where I wanted to see or at least talk to him, because I miss him so much, even as a good friend. Now this morning, just casually going through Grindr, I see Max' profile and was seriously shocked. It seems that they aren't dating anymore, just like I thought/felt it would happen. Now I'm more conflicted than ever to message Niko, because I really care about him as a person and I would like to know if he is fine. One time, it seemed like he was sad (looked exhausted on his whatsapp-profile) and I was seriously worried about him. I told a good friend of mine that I was worried and she asked me if I wanted to message him, to which I responded that I wasn't sure. I wanted to, but I felt like I wasn't in a position to ask him after what we went through.I know I just should do what I think is right for me, but I don't know it yet.Sry, I just needed to write that down to get a clear mind.
