Why would a guy be interested to me then stop talking to me?

Anonymous
I was talking and hanging out with a guy who I thought was interested to date me. Recently he would text me every week and asked me if I want to hang out with him during the weekend. I will always say yes and we will plan what we want to do together. Recently I notice whenever we planned to hang out for the weekend he would ignore my message whenever I contact him about if we're still hanging out that day like as planned. He would text me couple days later and make an excuse. Last weekend he texted me to plan to hang out again and I texted him then never heard back from him. Now I just recently found out he's in a relationship. What's up with this behavior? why would a guy act like he is interested and then end up dating someone else?
