When there is a gap in communication and connection after a break-up, you both get disconnected from each other’s daily lives and finding things to talk about that the other is ‘interested in’ is hard in the beginning, and is often trial and error.
The longer you are disconnected from each other, the harder it is to find things to talk about that get you more than polite or disinterested one word or one sentence responses.
You have to keep trying to figure out what things your ex is interested in and get back into your ex’s daily life. Once you’re back in, things get a lot easier.
