Guys, A guy I use to flirt with at a previous job has now become single?

So me and this guy him 23 now me 44 now, use to flirt at our previous job. He told me he wanted to have sex with me I turned him down. Well he had a pregnant girlfriend at the time. He is now single. I texted him and he is a Gemini mind you, well he is very short with words and when I texted 2 weeks ago he called me and I said don’t call as I’m beside my boyfriend. Well now he won’t say much at all and I’m wondering how long should I wait til I should tell him forget it?
