3-5 months? Years?
I don’t believe it’s a choice to love someone, always thought that’s an utilitarian concept:
Yes, you can “commit” to DO the things you’re supposed to do when you love someone, you can still care for them unconditionally, etc, but to rekindle attraction, after you’ve been in love with someone else, that I don’t believe.
I don’t mean it’s impossible, just that humans are wired in different ways and I’m talking from my point of experience.
