Do you believe in "If he wanted to, he would" ?

So, I come across a lot of content on social media that says that if a man wanted to (was interested), he would (he would be all over you, chasing you, initiating things, always after you etc.). Like, he wouldnt ever delay replying to you, and wouldnt ever propose to cancel or alter a plan. He would be always available.

However, I feel like this is black-and-white thinking. Like, there have been many times in my life where I was dealing with struggles, or having a bad time mental-health-wise, where I wouldn't have made the effort even though I really, really liked the guy.

What do you think?
