Should i stop talking to my cousins??

I am from delhi, So my cousins came to meet me after almost 5 years, they entertained me, they gave me a hell lot of respect, basically gave me all the attention i wanted. Now they will be returing back to where they belong from, and that's fine, eventually everyone has to leave after a certain period of time but they will only meet me again after 5 years, that's where i feel disappointed,  because they promised me a lot of things like they will care for me in the meantime, pick up my calls, listen to my concerns but they won't do that for next 5 years, and cutoff with me. (I know because the same thing happened in last past 5 years), It happens every 5 years they come, meet me, entertain me, give me all sorts of promises and we go on city tours/rallies and i have to choose one of them as my favourite but as soon as i choose any of them as my favourite and keep my hopes open for them to support me in next 5 years, they leave and ignore me in whatever way they can, doesn't even listen to some of my problems, and then come again after 5 years, so that i can choose the favourite one I am not sure if i should keep my connections with them or give them one more chance after 5 years. Actually 5 years is a long time and in the meantime i generally forget how they ignored me, treated me, didn't listen to my problems and once they meet me i get happy and hopeful because they make promises and meet me with their heads down, hand folded and pressed together against each other. Make a hell lot of promises how they will care for me, as if they are begging for me to talk with them, and that's where i melt and let all the things go. Let's see what happens this time, i have chosen one of them as my favourite and will be revealing the results after couple of days. P.S:- This is not about my cousins
