Is it normal to have a relationship that is dying on it's feet?

Okay my girlfriend and I have asked each other plenty of times before if we are right for each other. Reason we ask it is because new situations that pop up that seem to test how close we are to each other.

Like my other friend getting a crush on me and showing that affection with my actual girlfriend right there(Grabbing my arm, hugging, acting weird, you, get, the, picture) she asked me if I liked her and obviously got jealous.

Or the time three boys randomly asked her out, one a psycho, another a creep, and the last better than the last two. These boys asked her out in different ways, the psycho tried telling her I did more than smoke weed (Stronger drugs cuz gateway [She doesn't believe its a gateway] and said I was doing hardcore shit) and said how much better off if she'd dump me off in the middle of nowhere I would still find a place to stay. (Infering that cuz im a drug addict and that I really don't care for her or simplu cuz im colored but thats jumping to conclusions so lets leave this one before I start a rant)

Or the creep who tries to find all the bad in my life telling her I'm a wreck living in a shitty home with horrible people and that I'm gonna be just like them in the future so on so forth yadda yadda yadda blah blah diddly doo.

And finally the last one who wouldn't mind a three-sum who is also bi (I'm bi curious now in all seriousness I actually was considering that, told her that and she looked at me, "No, sorry but that would be just weird! Besides love trianges like that usually turn out bad in the end if it doesn't work." So we said no to him and the offer, [I did tell him I was open to it too if you are wondering])

Then our parent issues, spiritual experience(Yes I believe in the supernatural get used to it[Ojibwa, Native American]) me being a pot head, teachers telling us we aren't meant for each other(How we act and how different we are [She white good grades drug free calm and collected vs. Colored bad grades, pothead, gotta get my shit together and unorganized]<And no it's not really racial, that's and inside joke between me and her>) Hackers, Theives, school issues you get the picture we go through a lot.

We talk a lot, we been going out since end of middle school(8th or freshmen) but it was on a June 7th right after school was over.) But this time we were talking she asked me, if I still looked at her like a girlfriend(since our last breakup about a month or so ago) (These are real messages that i will show so please respect it is all I ask)[And im not showing personal so Im editing out our names and dates and locations and stuff.

Her: Hey serious question? Do you still see me as your gf? I get it if you don’t, I’ve put so many breaks on us it’s just like wow.

Me. Kinda yes and kinda no, lucky im stoned so I can actually put it in words, but the feeling is just as simple as we are close a lot close and another part says it's too close, chosing words part isnt there but that's how I see it (I was in a middle of a wake n bake watching the sun raise to start my day)

Her. Non of the breaks are because of you, It’s either my depression and I’m like you don’t deserve to worry. (Editted heavily she was trying to explain every detail)

Me. I know dont worry you don't need to explain, I won't go a day thinking about hate. I understand what you are going through (Editted heavily Mostly because I was explaining why she don't need to explain anything that contain deeper shit than I can share on here)

But anyways you get the picture so this question is for us(She knows I'm posting that's why I included the text) Do you think we are made for each other? We are pratically oppisite but have these situations coming up almost all the time it's got up wondering...
