Search Results: not over his exes

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?

Last summer a guy asked me out but plans fell through. He continued to like me up to now, we started "seeing each other" We definitely hit it off and have a lot in common. But its only been a week and he is saying things like if he had met me sooner he wouldn't have wasted his time on his exes and how I'm a keeper. i feel like he over compliments me and he also talks about the future a lot. He's graduating this year and I'm one year behind but we plan on going to the same school and he's implying he sees in continuing till then. am i getting in my head or should i be worried that he's coming on so strong? what should i do
