Search Results: asking for second date

We met on tinder and yes, there are a few guys on there looking for long-term relationships and not hook-ups. Before we met, we already discussed we both want a serious long-term relationship. His last relationship was 9 years long. He doesn't like hook ups and doesn't sleep with people easily. He is 32-years old working in the medical field as a registered nurse doing cancer research. I'm not sure how busy his job is but from what it seems like, he's mostly always very busy at work.

He told me that he really likes me and nowadays, it's difficult to find someone who is sweet, normal, and beautiful at the same time. I know he totally can lie but in actions, he put effort to show me he cares about me. We've only met each other twice and we had sex on the second date. I told him that it's a bit too early but he apologised afterwards. He finds me really attractive. After sex, he was asking me questions about my exes and he wanted to make sure he was not my rebound (since I ended a long-term relationship a year ago).

Last night, I told him that I like him and that I find him pretty amazing inside out. I also told him that I don't sleep around and I don't do hook ups either. I confirmed to him that I am not looking for hook-ups. He told me exactly the same thing. He really likes me and he's not looking for just sex. We then set up a 3rd date on coming this Saturday.

This morning at 10, I texted him "Good morning, I hope you're having a good day". He did not reply and it's now 4pm. I do realise this guy texts a lot more at night than during the day on weekdays. I also notice that he's not the type of people that always have his phone. He never takes his phone out when we're together. Maybe when he's at work, he doesn't text. But I once, I did caught him reading my text but not responding till hours later.

Am I thinking way too much? Or, it is a red flag? Should I date other guys too?

I met someone for the first time through social media (we had mutuals and have been online friends for a while). We went out to grab lunch but he's kinda shy so it wasn't explicitly said it was a date. So I didn't take it as one. But when the bill came, the waiter didn't split it, and he just put his credit card ready to pay. I thought he was just being polite, so when the waiter came back I asked if he could split it and gave him my card too. The guy I was with paused for a second and then didn't say anything.

Im not sure if it was a date and if it was did I offend him by asking to split? I mean he didn't insist to pay so I figure he was just being polite initially. But I have no idea. Help me understand please.
