She had to get rid of an ex and was just out of a 2 yr relationship.the last 3 years we've had sex a few times and don't think I'm in a friendzone.We've had a few arguments that friends don't really have,couples do.this year we had a fight because I tried to get more out of it and she said she likes me and always calls me good-looking but is afraid that if it didn't work out then we wouldn't talk again.She seems to be afraid of losing me.Im wondering could you help me out here?She likes her space and doesn't really get into a relationship for anything more than a year or two at most from what I've seen
2nd question:
We had that argument and didn't talk really for months but we got back talking recently and she now has a boyfriend and we were out together catching up and I said I was seeing someone and she keeps referencing her boyfriend with a lot of things.Is she trying to make me jealous or am I reading too much into that?

You are in the "friends with benefits" zone, where you both are free to see each other and have sex but without commitment to be exclusive, so you both can see others.

The thing is why is you both seeing someone else, a point of her wanting to make you jealous? What if she feels you are trying to make her jealous.

As you have both crossed a lone beyond mere friendship, the lines of feelings has also been blurred since you didn't know that you were in the FWB zone. There is no way to know if you, or her for that matter is reading too much into this as the whatever it is you have has never been defined by either of you. You just did what was convenient.
