Can anybody give me some boyfriend advice please?

Basically I've been with my boyfreind for over 3years and at first he was great, we always went out to places together, he was always complementin me n made me feel like I was the best thing in the world, he was just so loving and now its like I go out with the complete opposite. Its now me that has to suggest us goin out otherwise we just end up sat in watching telly and when we do go out its also me tht ends up payin most of the time, I know I should definatley pay for things but so should he and its no where near equal. Its not like he carnt afford it, he gets payed more than me n I stil treat him. If I ever want a kiss or cuddle I have to blumin ask for it otherwise I just won't get one, how's that a relationship? I've tryed to sit down and have a coversation about it but he just doesn't want to know, its like he jams up wen ever I bring it up. He says there's nothin up and that he definatley doent think he's changed in any way. How can he not see it? I've also tryed a more casual approach in tryin to talk about it hopein that this might make him open up more, but stil nothing. So every few week wen I bring it up again he just now refuses to even talk about it n completley ignores the question. I need to get to the bottom of this because its something that's makin me feel really unhappy in the relationship. I understand that in a relationship people do change and they don't make as much effort I can accept that but I can't accept someone makin no effort at all. I know u may think why don't I just call it a day but the truth is I really don't want to I want to fight for our relationship and I want to put things right and make things work. But how do I make him see this? How do I make him see how much he has changed? Any advice would be great please
