Hi I have broke up with my boyfriend the other month we had sex but he fancies my mate but she don't fancie him we do things together as long as she don't find out cause he thinks she still loves him he seems to switch between us can you please tell me if he is using me

I would have to say it seems that way. I would stop seeing him all together. It is not worth you getting hurt or even some kind of disease because he cannot commit to one woman. Trust me you will be far better off.

but she dont fancie him

can you please tell me if he is using me

You broke up with him so WHY are you still seeing him?

Why are you still having sex with him? Are you using him??

He likes your mate so why do you want to be sloppy seconds?

Where do you think things would stand if she finally decided she did like him and they were bf/gf do you think you would still be in the picture?
Yes he is using you but you are using him too.

Hey, if you don't mind just having sex with anyone, what the heck, not my life. So what is your question, you broke up, but still seeing him, so you are not really broke up. You are having sex and he likes someone else and you know it.

So to be honest it is your choice, although you seem to be making bad and poor ones, only you can change your life style
