Hi everyone, I'm not usually the jealous type of person but this boy who I known since school likes me and another girl called Amy and wants a threesome and he keeps talking about her to me - I'm not interested in having one!!! Like I said I'm not usually a jealous person but he keeps talking about her to me and telling me that he thinks about us 2 being together and having a three-way!! I don't know what to say to him, Please help me

Yep,that's not normal because he shoul accept your position.
If not,you should leave him.
