Hard to tell if it’s a true twin flame or just a catalyst for self-expression lessons.
Is your throat block worse specifically with him? Like full shutdown around his energy? When you imagine sending one honest sentence, does it feel steady and relieving, or urgent and spirally? That’s been my clue for aligned expression vs. chasing.
The masculine twin often won’t start truly awakening until they receive something real and unfiltered to process. His humour-as-defence tells me he’s pre-awakening. Masculine twins typically need a concrete emotional truth dropped right in front of them before their walls even know they need to come down and that doesn’t mean you pour your whole heart out in one message. One honest sentence can do more for his awakening than years of energetic work done in silence.
The feminine holding back can accidentally keep the masculine asleep way longer than necessary.
Day by day for me at the moment. I’m not even in total separation with my TF right now so maybe I shouldn’t be the one weighing in, but it treats every single situation like it’s identical when these connections are so wildly different from each other. Just feels reductive.
Obviously everyone’s situation and twin dynamic is a little different but… My twin and I have traded back and forth, runner/chaser. Right now I’m kinda holding the chaser torch. I have been communicating nonstop! 
Just a dump of emotions and thoughts and triggers and growth issues, poor guy! Anyway, he has a sporadic communication style which is maddening, @eunichick I feel you about the breadcrumbs!! I feel like I’m pouring my heart out, and met with lukewarm! So I asked him flat out if he was needing space to process, that I was worried my communications were changing how he felt about me. He replied immediately with “I Love you, no of course I don’t need space, silly!” And still his communication style persists. 
It’s for sure triggering, so my new tack is to make sure of my motivation for sending emails, is it to illicit a response or to send love? My two cents!
@MeAgain, my Twin has currently adopted a very indirect communication which to most would seem very sweet and romantic, but some days it makes me wanna scream, “Why can’t you just say what you wanna say?” We have been communicating through music. Which is something we have always done, but it was also during a time we were actually talking and texting. Now. He just sends me music, and I “reply” with a song too. He even said after sending a song last week, “This communicating through songs is kinda cute”. Yes. It is. But if that’s how you wanna communicate with me, we can do that. But don’t just drop off the face of the earth for days/weeks then come back with a romantic song. So infuriating 
I know exactly why I’m not reaching out and I never will. No way. I think you need to look very hard at that choice. Every situation is different. Not the twin thing alone. You need to look at it as your journey. Not anyone on here and certainly not your twin. What choice is good for you? What will make you feel better? I know from experience saying you can handle silence and actually being in that place? Two very different things. In my case the choice has to be his. I will never allow myself to be in a place where I always wonder if he chose me. He got something sent here that gives me more than enough reason to contact him and I still didn’t. I will never put myself in a situation where I reach out to a ghost and sit in pain. I trust the divine. I know I will be okay no matter what.
