He mentioned the possibility of a 4th date but hasn't mentioned it again

Hi you guys!

So basically, my problem is that I find this guy I’ve been on 3 dates with a bit confusing. We met online, and I was the one to ask him out on the first date (was this a mistake from my side?). We went to see a movie and he then asked me if I wanted to grab a coffee afterwards and we ended up talking for 2 hours. He texted me only about an hour after the date telling me he had fun and asking me out on a second date.

On our second date we were at my place watching Game of Thrones, and then he asked me if I was hungry and as I was (and so was he haha), he took me to an Italian restaurant nearby for pizza, he paid for dinner. We then came back to my place to watch another tv-show and always when one episode was over he asked me if I was tired or if we could watch one more episode, and ended up watching five or six episodes. The date went great and by the end of the date I asked him if he’d be interested to see me again next week and he said yes.

The following week we went bowling, and after that out for a drink, and he said that he would have to be home early (because of a pain medicine he had to take at a certain hour which made him tired and unable to drive). When we had finished our drinks I said “I’ve had a ton of fun, but I’ll let you head home to take the pain med” but then he asked if we could go to my place for a cup of coffee.

The funny and amazing thing is that we went to my place for coffee and ended up talking for about 4-5 hours which is insane because it was only the third date and I’ve never experienced anything like that before!! He headed home at 3 in the morning and said “Next time we’ll chill at my place” to which I said that I’d love to.

We haven’t gotten physical yet, he kissed me on the cheek after our second date and after our third date when we hugged and he was pulling away I just went for it and kissed him. A quick kiss goodnight, no makeout sesh.

Now it’s been a week since the third date and he hasn’t mentioned a fourth date or invited me over to his place. I should probably mention that we message each other daily on Whatsapp and the initiating is quite close to 50/50.

Sorry for the long story, but my questions to you are:

– Is he interested? If so, is he just shy and taking things slow (he told me that his ex is absolutely crazy, maybe that affects?) ?
– Why hasn’t he asked me on a fourth date? Is he losing interest or just taking time to process things?

I’m just a bit confused because he seems interested but I’m afraid that maybe I’m somehow misreading the signals.

Thanks in advance, could really use some insights!! :)
