He lied to me for sex?

Hi everyone. Feeling awful but could use insight. I met what I thought was a great man on a dating app. We had a fun first date with dinner and a long walk. We got coffee on the second date and spoke about our intentions. I told him I did not want casual sex because I’m interested in building something. I have kids and he doesn’t and his job will make him move in several years temporarily. We both knew this about each other going in. We both said we want a relationship. On the third date, he spent the night and we were intimate. The next day we got lunch and spent some of the day together before he went to work. Today I said I enjoyed our time and was interested in what he saw going forward. He waited hours to reply and said that he likes me but “has worries about anything long term due to my kids and his having to move. And just ‘hanging out for fun’ might be better.”

We specifically both said we did not want anything casual. Then we had sex and suddenly he wants to just “hang out for fun.” I gave him a chance and I had hope for him. I am hurt and upset and this has made me feel very used. Did he just lie to get what he wanted?
