The best bit of general dating advice I can think of is to not be with someone because you want to be with someone, but because you want to be with that specific person.
The best way to meet people is simply to be as social as you’re comfortable being with without looking too hard for potential partners. Spend time with friends, get to know their friends, and the friends of their friends and so on. Over time, you end up meeting certain people who you “click” with and you start spending more time with them naturally and sometimes that’ll turn into a relationship. This is not the same as “not trying” like some people think.
It is better to get to know people, then figure out what kind of relationship you want or are willing to have with them, rather than deciding what kind of relationship you want and then trying to fit someone into that mold.
If your friends and family are warning you away from someone, it’s a good idea to take their opinion into consideration. But, on the other hand, it’s not a good idea to be with someone just because you think others would approve of them.
You’re public access, so I’m assuming you’re pretty young but, as you get older, stay off of dating sites. They are a toxic cesspit.
Not sure how helpful any of this will be to you but, as far as general advice goes, it’s the best I’ve got.
