What's the logic behind this relationship?

Even I dislike him after reading this, and her.

Why would any decent person accept a car as a gift from a guy they claim to hate?

She takes his money and gifts??

I was obsessed with one well not with her but when she cheated on me after the perfect relationship (we were 17 and went to lose our virginity together but neither of us fulfilled and continued with foreplay) but other than that we had something there, I thought we were high school sweethearts that will marry and have kids. Then out of the blue she cheated and also chose to be with him over me. We stayed friends because I still loved her, then her new guy wanted to stab me, so there was drama there and me and a friend drove around to give him a touch up and show him we take those threats seriously. But he hid away and we gave up. Then me and this girl stopped talking because of this drama and she heard people talking that I was a dealer, associating with gangs, in a way it helped me push her away.
Months later she had trouble with him, told me she was breaking up with him. I moved to the western suburbs (opposite side of the city) after Mum kicked me out of home, she tracked me down and caught public transport to the house I lived at. I got worried because where I was it was nowhere for her to be on her own.
Then she went to kiss me after talking, I said you don’t want me back now. I’m not who you loved anymore. So I observed to her what kind of life I was living. I told her to never come here on her own again because it’s too unsafe.
So I drove her all the way home back in the east side.
When I dropped her off I told her, this maybe the last you will see me if not the next time, that’s my life now (back then). I grew up.

it's not logical. emotion isn't often logical. especially love, infatuation, whatever.

Does she actually accept the gifts?
Edit: I just saw below that you said she does.
Then she's her own worst enemy and it'll be her undoing sadly.

This sounds like infatuation, not love.

From Symmetry Counseling page

Everybody matured at their own pace. I was obsessed with a girl for a long time.

It wasn’t until I let myself experience life that I forgot about her.

Some people like to be hated, it makes em want to pursue them more cos their confirming all the taits they think of themself, so they are "real" but it can become super abusive and toxic for both parties, that's one intrepation anyway

Is she accepting the money and gifts??

I think i saw that movie . Jennifer Aniston? Ryan Reynolds?

Is this what they called 'love is blind'?? 😂😂

Obsession isn't rational.

She's a crazy user and he's a crazy stalker.

WHAT THE HECK

He's masochistic. He loves to be hated.

In his mind she loves him. In his mind they are in love. He needs psychiatric help...she needs a restraining order. If she marries or has children with someone else he may lose it and God forbid kill her. Holy Moses...he is scary.

that's the mind of a serious mental ill stalker..

He is delusional, mentally ill.
