If it was arbitrary conversation, I could deal with it as long as he made up for it in other ways. But, if he did that when I asking him legit questions etc..., I would nope out. I don't want someone to ignore me for the hell of it or because they can't be bothered.
if I'm into someone i invest time into them. ill go out of my way to talk to them. if they really can't care to do the sam consistently then it becomes harder for me to build any sort of deep connection with them.
I would rather Skype/calling in general. Texting isn't a huge deal, but if he can't communicate with me at all, then it's a no go. I had a boyfriend who rarely texted me, but our communication was terrible. It was a huge reason I broke up with him.
