Should I end this or continue talking to him basically on his terms?

I was going out with this guy for a month we went on dates and hung out together basically everyday for a month. He left to Europe for a trip with his family for a month and since he’s been gone he’s barely reached out to me. When before he left he told me he would call and face time me. He reaches out very little and I don’t know if it’s because he is genuinely busy like he says he is or if he lost interest. I texted him saying I thought it wasn’t nice that he didn’t reach out once and he apologized and said he really likes me and hanging with me but he’s just so busy. He’s coming back in a couple days and we don’t really talk that much anymore. Im hurt and i don’t feel the same way i did about him before he left. I don’t understand why men say things but so obviously a lie because there actions don’t match up with there words. Last thing I said was hope ur having a great time. See you when ur back maybe. And he just said yeah everything going well might buy a factory here! And didn’t answer my see you when ur back. I answered and said cool! Why do u need a factory tho lol. And he hasn’t answered. I don’t wanna play games but I don’t wanna come off to strong either. When he answers considering he’s probably gonna be dry as usual should I even answer his text? Or should I stop answering and if he cares he’ll reschedule out again?
