Please help me make sense of this: was he just looking for sex/sth casual or an actual relationship?

So I met this guy on Tinder, he texted me quite consistently, was quite flirty but asked about my interests etc. and suggested a 1st date at his place. I asked to meet in a public place instead, he agreed and suggested a bar that's close to where he lives. We met, he was kind and respectful, we had really a lot in common so I liked him. But after the date, he walked me to his house, despite me telling him earlier that I didn't want to go to his place (I made an excuse and left). The next day, he asked for my IG and said he was deleting Tinder, which I took as a sign that he liked me.

He didn't text me for a whole month (we were also both out of town because of Christmas break), just kept watching/liking my stories. I texted him 2x after a month: first to wish him a happy new year and ask when he's back in town, and then again after he was back to suggest meeting up again, to which he enthusiastically agreed. He postponed the 2nd date twice bc he was busy, which is fine, but he did suggest grabbing food and then going to "hang out" at my place. The date went great, I felt like we had a great connection, talked about serious stuff like our pasts, him wanting kids someday etc. After we got to my place, he suggested watching a movie in bed, during which he attempted a few times to have sex with me, which I refused (Ik it's weird but I wasn't ready). He was nice but seemed very disappointed in the morning and left earlier than he planned.

Afterwards, I didn't hear from him for over a week, until I texted him to ask if he'd be down to meet again, to which he agreed, but when I asked when he's free he said "I'll let you know" & then I didn't hear from him again for a few days, until I texted again to say I'm free the next weekend if he is, and we agreed to meet at his place.

I feel like there are mixed signals, but do you think he just wanted sex from the start and lost interest after I said no, or was he genuinely interested but lost interest for whatever reason?

Please help me make sense of this: was he just looking for sex/sth casual or an actual relationship?
