Especially as a guy?
The girls all have around 70 or 100 likes, but they guys usually only like 5 or 20 or so

Dating sites/apps have more guys in general and are more likely to look around on those sites - so women will naturally have a lot more.
When I 'boost' my profile on dating sites, my likes go way up, but then afterwards ill go days without one. Girls don't often initiate messages I find as they already have a lot initiated by guys. I've also messaged girls who have 'liked' me but do not reply.
I don't think likes mean anything - they might be on the fence and just click 'like', or might press it by accident.1
