Is my ex making me jelous?

I asked my ex today if he wanted to go the cinema.. as friends.. at first he said he didnt know because he didnt know what he was doing then later on he text me saying yeah we can go if we want because he has no plans.. however during the time i already organised to go out with friends tonight for a night out.. he said nvm then.. he doesn't have plans probably just a night infront of the tv.. but now all of a sudden he is going out with his mates now.. after he told me that he had no plans.. were both gay and im going to liverpool tonight i said might try out the gay bars, he is off to canal street in manchester (the gay village) i just think why has he suddenly changed his mind now? and decided to go to the gay village when he could of gone to our local town for a night out?.. what is he doing :-/.. he doesn't love me anymore but i still love him.. im worried incase he does anything with another man i.e a snog or something :/? is he trying to make me jelous now because im going out now.. but he's the one who said he isnt bothered anymore?? we've been split up 2 weeks tommorow :-( hmm confused and worried!!
