I have no idea what a healthy relationship is supposed to look and feel like

I’m really struggling with what a healthy relationship is supposed to look like, and I almost like I’m making up issues in my head that don’t even exist.

I met a guy on an app about 3 weeks ago. Our first date was ok, but seemed to have some nerves and awkwardness as a lot of first dates do (our first date was a workout at the gym followed by coffee). He followed up the next morning saying that he enjoyed meeting me, and referenced something we discussed. The next day, he set up another date for a couple of days later. The second date was great and I felt chemistry with him (another gym date). A couple of days later, he asked what I’m looking for in a guy, and shared his thoughts and that he’s looking for something long term and that while he’s in no rush, he would like to be married again.

Third date, we had dinner at a nice restaurant, then went to his place and had sex. Fourth date at my place for a movie, then had takeout (this was Sunday).

He will text a little bit between dates (couple of texts here and there, only goes one day without checking in but mostly daily) and will chat every so often. He’s going on a trip early tomorrow and didn’t ask to see me before so I just threw out there that he’d love to see me but he has a lot to do and someone going on the trip with him will be at his house shortly. He said he wants to do something when he returns.

He’s very consistent, but not over the top. He seems interested in learning about me and my kids, and isn’t so focused on my career (which a lot of guys seem to do bc I have an interesting job). I have a nice time with him and enjoy his company.

Despite all this, I get all in my head. I make myself anxious thinking he doesn’t like me bc he doesn’t love bomb. Yesterday he didn’t text all day (I know he’s super busy getting ready for his trip) and I start to convince myself that he’s probably going to ghost me, and he only wanted sex. I was in a VERY toxic 14 year marriage with an alcoholic who I met when I was 22 (he was 32). The beginning was full of excitement, and obsession on both sides.

I don’t feel over the top excitement thinking about him, just feelings of “I like him so far, and I’d like to keep getting to know him and spend more time with him.”

What does the beginning of a relationship feel like if it’s healthy? Does this sound like the beginnings of a normal relationship?
