Why did my ex contact me outta no where after so long?

he is bored you are something he has known and that is what hes doing. his mom is telling him to hook up with you but is he wanting this nope i can guess and hes just playing like he told you and therefore you are stupid to put up with him i would not speak to him any more and move on like you have planned not looking this to be anything but using you and more i suggest you block him and keep moving take care and good luck
