What is a woman thinking while in a relationship breakup?

My girlfriend and I broke up?

I still love her, we were realy close when together.
Then she started instigating these major fights and criticising me more and more.

I reacted at the time and got really fed up with her.
Now that she’s gone I realise that I didn’t want to fight.
I was really in love with her.

She won’t speak to me at all now.

Sent her this email:
I know I hurt you and I’m sorry.
Don’t you think, you’ve ignored me enough.
I would like to be your friend at least.

Look, I’m a rational person and I’m aware that I don’t want to be a creep.
It’s just that you disappeared and it’s weird.
We got so close and now I don’t know where you are or anything.
I know things got bad for a while but I care about you.

Whenever I talk to anyone about you it’s always with respect.
I like you as a person and I think it’s a waste just never talking again.
I’m gonna try not to send anymore emails after this one.

I just think it’s worth valuing what we had.
You were so important to me and I’m glad I met you.
I don’t know how things are going for you now, I hope your okay.
If you need a friend, Oni, I’ll be here.

She sends back this:
Contact me again (ever again) and I’m telling the cops your harrassing me.

What is going on with women?
Why don’t they care about love?
How can they be so heartless and mean?
