There is this guy at work. He has been in a relationship with this girl for 2 years. All three of us work in the same team.

I've been shagging her for the last 3 months. The main reason was, this guy is a little beta cunt. He thinks he owns the place. And when it doesn't go his way, he goes to manager like a cry baby.

So I've been flirting and chatting to his gf, and at during a drinks night out. I pulled her.

She became a plate. 3 months I've been shagging her (she still lives with the BF). However...

She started getting clingy, asking if she will meet my mum. I've been distancing myself. But it's making her more crazy.

Just today. I've had 13 missed calls and 9 texts.

What do I do?
