I am so (irrationally?) scared

Hello! I would be grateful for your insight.

I am in mu early 30s and apart from one long lasting relationship, my dating life was pretty much kaka. I had my fair share of disappointment and incongruent men.

I am soon relocating to another country. I am currently in the city when I will live soon. I opened my Tinder mostly to entertain myself with some dates. So I met this guy one month ago, he wasn’t my type at the beginning (because of his physical appearance. Not saying that he is unattractive, just a guy I wouldn’t look at in a bar etc.). We have been seeing each other every 3-4 days, sometimes more. I have to say that he is really creative, if it comes to dates. Usually before the supper we do some other activities, like visiting museums, playing minigolf etc. He even heats up my plate, before serving me a dinner and preparea me gin tonic with a hibiacus flowers 😹. Those are only examples, but I feel well taken care off and safe. I started to develop feelings, still careful, but I enjoy spending time with him a lot, as we are compatible on the intellectual and emotional level.

So, everything is great, but I am just scared. I was disappointed so many times that I cannot help but think that he is nice now and then he will show me his dark side (btw, we already sleep with each other often). I keep my insecure thoughts to myself, I don’t act on them. We don’t texts or call ourselves, except from making plans, which I find great.
I am 32 and he is 42, we are both from Europe but from 2 different countries.

So my question is, should I proceed with caution, because it is too good to be good? Or maybe should I relax and stop overthinking as maybe he is genuinely interested and a decent person?

I am sorry, if the question is silly, I just feel thaty mind works against me.
