For the last three days, all our conversations at home have been superficial. My spouse is constantly busy on the phone, yet they’re sitting next to me. They’re active on WhatsApp with their mother, but ignoring my messages. I feel like there’s a problem between us, but I can’t quite understand what it is.
my ex-boyfriend went through a phase like this too. he was always on the phone, but not with me. eventually, I found out he was texting another girl. hopefully, that kind of thing isn’t happening with you.
Do you have any doubts about what your mom said? Because it seems focused on her but quiet with you. Is the issue between you two coming from there? 
@kahvebitmeden actually didn’t have any problem with her mother, as far as I know, but this is the first time there’s been this kind of coldness. She constantly listens to ‘personal development’ type videos on YouTube; could that be influencing her?
It seemed silly to me to just cut things off and assume someone is writing to someone else. Everyone can have difficult times in their life; don’t think that communication will be severed all of a sudden.
You need to sit down here and ask directly and openly. The topic of YouTube seems a bit strange; there can indeed be people who drift away with the mindset of personal development. However, in this case, it’s important to speak clearly again. You can also consult an expert for a definitive answer.
So the YouTube thing has gotten really weird.
@yazipsildim you’re absolutely right, just pulling away to another place isn’t the solution either, but the person in question might have valid feelings too; if you feel coldness, you probably don’t feel it for nothing 
You can’t know without talking.
Could it be the influence of her mother?
