In the beginning of the day,my EX's friend asked me would I go back out with my EX.I said no & I guess my EX heard me.. His friend then asked me, why not & it got super queit in the room. My EX's friend saw him staring at us & said that my EX looked jealous.

In 3 period I was sitting in class with my best friend talking about a boy I fancy.. suddenly my EX came over & I began to talk about the boy I fancy.. my Ex was joking around & saying that I would sleep with the boy & I jokingly said I would.. my EX started to insult me, so I cursed him out.. after I cursed him out, he began to flirt with my best friend.. he said that him & her belong together.. he also kept messing with her.. when he was done messing with my friend, he started to insult me again.. so I yelled at him & he left me alone the whole day.. but the thing is, I really felt like he waz trying 2 make me jealous.. now I deeply HATE him & I'm pretty sure he knows I do

Some background history on my EX-he told me he still liked me like 2months ago. *I'm now finding out how immature he is. *HE NOTICES LITTLE THINGS I DO (that I laugh when I get nervous). :D *not to long ago he waz asking for advice, about some girl.*I sometimes catch my EX staring at me.*he'll do sertain things to get me mad.

p.s-our friend relationship is really complicated.we can both tell we still have feelings for each other.I hate that I like him still!:mad: I mean its weird, there are days when I just crave him(not in a lustful way)& then there are days like today, that I hate him.When I look into his eyes or look at his smile, I know something's there.

So do think he still likes me & was trying to make me jealous??

That's hard to say. If he tends to act a little immature then he most likely is trying to make you jealous and as far as the butterflies one minute and the I want to choke you the next, honey that's normal. Get used to it, it will always be that way. You'll come to learn that no one can make you happier and no one can make you angrier than the ones you care for.

It sounds to me like
He hasn't emotionally detached from you
SO he wants to make you jealous
He sees your interest in other guys a threat to him
Because he wants to be with you
And/or he could be in the "IF I can't have her nobody can" mentality.

At any rate it is an immature double standard.
Since you don't want him back it doesn't matter just move on with your life.
