You guys manage to turn any thread into a fucking shit tip, congratulations for being the most dramatic killjoys on the internet.
Now, advice:
I've been in relationships with obsession on each end of the relationship, I've been obsessed over a girl and I've had it back and what I can say is that obsession never works out for either of the pair. She'll end up being over-clingy, annoying, frustrating and overall just a pain in the ass if she's very obsessive over you. Don't fuck and chuck, although I'm not sure of your age, if you're 13 or younger you're unlikely to do this anyways but the point is don't be a little fuckboy, if you're into the obsessive stuff then sure, go out with her just prepare for the four consequences I previously listed.
Here's a section of an article I found that pretty much perfectly describes this.
What do I mean by love and fixation?
Well, when you love someone, it is pretty effortless. It is true and pure – you don’t need them to be any certain way. Heck, you don’t even need them to be your boyfriend or lover. You just simply enjoy them as a person and you’re happy with them just being who they are. You don’t need to possess them. You don’t need a title from them. You just love having them in your life and they love being in yours, whether it’s as friends, as lovers, or as life partners.
Again, I have to emphasize that it’s effortless and characterized by you just simply enjoying each other. You really “get” each other. You laugh together. You don’t need them, but rather, you just enjoy them.
That’s love. That’s compatibility.
Fixation, on the other hand, does not feel pleasant. It does not feel good, but it does feel very urgent, very important, and very stressful.
When you’re fixated on someone, it feels more like you’re suffocating. It feels like you need them… like you must have them treat you a certain way, give you a certain relationship title, or somehow prove their commitment to you. You feel like until you have this, you are not OK and will not be OK.
When you’re fixated on someone, your relationship ceases to be about enjoyment and effortlessness. Instead, it is more like you are gasping for air, desperately hoping they’ll give you whatever it is you think you need from them.
Granted, even good relationships have a little bit of fixation mixed in with them (I must emphasize a little bit), but it is only during very occasional occurrences like arguments or when one or both partners are stressed. In general, though, compatible people have very little, if any, fixation in their relationships…
People who have good relationships observe how they themselves feel in a relationship with another person (whether it’s a lover, a friend or a co-worker). They observe if their connection to the other person feels like love (good) or obsession (bad).
If it feels like obsession, they drop it like it’s hot.
The point of this is mostly focused on the last few paragraphs, if she's obsessed (fixated in this context) then it's more like she doesn't love you but treats you like a drug and needs you, the relationship's not gonna be very fun and more one sided - her side in this situation.
