MY girlfriend and I are in university and have been living together since we started our relationship last February.

For the past year, we have argued about many things, but managed to overcome each problem. Our relationship finally became stable this year.

However, two months ago we started the new university semester and she said she needed more friends so I let her spend more time with her friends during the day. Then she found out that one of them liked her.

She asked my permission to flirt with him and I allowed it because she said it was just for fun. Before the mid-term break, she spent all her time with her friends during the day, and at night, she spent most of the time on MSN. I didn’t think it was a big deal.

But after the break, she changed. She spoke and acted differently and I noticed that she was getting more into the guy she flirted with. I scolded her but things are still the same.

When we first went out, she said my only weakness was that I wasn’t rich. This year, I had extra money from a study loan, and used it to buy all the things she wanted. But she used them to show off and flirt.

We’re now just good friends and she promised to get back with me after she has thought about it. I can see she doesn’t mean it. I love her so much and have given up everything for her. But she treats love like a toy to make her happy.

So, now I want to teach her a lesson, so that she will wake up and realise that what she’s doing is wrong. I want her to lose everything, to suffer and to feel what it means to have her heart broken. But I will be there for her when she collapses.
