Maybe this is off topic as well, but it’s my take on dating. I think it pays to be really discerning, patient enough to play the long game of getting to know someone properly and be willing to walk away if you see red flags/deal breakers, even if they seem nice (because “nice” can be a good act and genuine niceness should be a basic requirement anyway). Of course these things don’t guarantee a great relationship but they can help weed people out you might not be a good match with.
