I'm actually surprised that everyone
's on the seme's side and they say the uke should speak his mind but I think it's the seme who needs to clear things out. The uke has already expressed his discomfort with the situation and asked a very clear question. What else he should do when the other guys is not talking at all.
right, he's thought about the things that happened in the past that made him uneasy about the relationship and is now explaining it to him to make sure he doesn't feel sad again. and even after this seme still clearly hasn't figured himself out. he needs some serious self reflection before this will ever work.
y'all do realize real relationships are different from bls right? the comments saying uke is making a big deal for no reason are out of touch. his feelings of wanting reassurance of love in the relationship are very valid, especially looking back to the fact seme still never said i love you even back when they dated before. love languages are different and if he still isn't reassured about seme's feelings for him, he's valid to put distance between them, especially if seme can't even do the simple thing of saying "i love you".
