toxic relationships

i've only been in relationships that were extremely toxic and really fucked me over. you'd think it'd make it easier for me to spot red flags right? but really it just makes it more confusing for me when it comes to what's normal and what's a red flag.

how did u guys know u were in a toxic relationship?

where do u draw the line of possessiveness with ur partner???

edit: this is bc of my current bf does little things that i feel like may lead into something worse but i'm not sure if i'm overthinking it. i love him so much it's insane i've never had a relationship this good but then somethings seem off. we're in a bit of a thing rn that's seems weird.
