Still haven't texted him. Should I?

A couple of weeks ago I postet a longer text if I should text the boy who broke my heart half a year ago. The problem is that I still have these hopes and wishes that it could work out between us two, but if so, I would like to start as friends and see where it goes. A couple of days ago I was in a nearby city where him and I would always meet the few times when we went out (as friends) and while I was in that city, I went on Grindr (where we initially met in August) and saw that he had a profile again. He had it deleted because he was dating another boy while I tried to stay friends with him, and guess what, I saw that other boy also on the app a couple of weeks ago. I immediately understood that they aren't dating anymore. Which kinda makes me happy, but also sad, because I'm sure that he felt bad because of that. But now seeing him again on Grindr, apparently single, makes me feel as if I really DO NEED to text him, but I'm not sure. I also saw him on Hornet a couple of minutes ago, which is why I'm asking myself if he's looking for dates or more (which I don't think, but if he does look for more then I am seriously surprised because he always said that he would never search for a hook-up).Of course I miss him as a good friend, and I try to get over him by dating other guys, but something always brings me back to him and then my hopes get up again. So I'm thinking... I think that I'm definitely gonna text him, but I'm still not sure.. Should I? And WHAT should I text him? Do you have any advice? I'm struggling with this for a couple of months now, and somehow I interpret it as a 'sign' that I saw him on Grindr, although I try to not believe in signs and destiny anymore (because of him).Sorry for the long text. I would appreciate every piece of advice. Have a nice day!
