I don't know if he is interested in me?

i met a guy on a dating app. I prefer meeting in person than endless texting, so after we text few times and when he said "we should meet over drinks someday", I asked him if he wants to meet on that weekend. He said yes but he postponed 3-4times. We didn't meet and stop texting before both of us went back to home country for holiday. After few weeks, he text me and we start texting for few weeks. After both of us came back to the US, he asked me to go out for drinks and we spend the night together. We text each other like before. For the second meeting, I said to him we might be able to meet after I finish my dinner with my friends, but at the end we couldn't meet because I spent my time with my friends untill super late. After that night, he doesn't text me like before (I'm the one who text first) I like him and want to know about him more, but he isn't interested in me?
