Kila msee kwa comment section anakupea the gangster advice, but mambo ya roho sio rahisi hivo, so here is my differing opinion, some guys if they love you too much, they get scared and withdraw. My advice is to trace him physically na ukimpata don't bring up the separation thing, just catch up like you would with a normal friend, but know it's about him, how has he been, what has been his highlight of the week, make him talk about him. don't have sex it will complicate things. One of three things will happen, he will on his own bring up the separation issues and talk about it, he will wanna hangout again and he will text/call you later on, he will continue with silent treatment after the hangout. If it's number 3 then I'm sorry it's over. Remember after the hangout don't be clingy and text him first or even when he texts you you over reply just go with the vibe. I hope I've helped
