3 years, is is too long for us? Options

My boyfriend and I recently made 3 years. But its like he doesnt act the same anymore. He rarely says sweet things anymore. I really need that attention from him though, to know that he cares. I've tried numerous times talking to him about it...but he only gets angry at me for it. & its like lately he wants to spend less & less time together....like when i'm like "well u can stay home" instead of sayin no b/c he WANTS to see me he'll be like "no, u'll get mad" Does this mean he doesn't care for me anymore or is he just having a hard time showing me that he cares? sorry if i left anything vital out

maybe he just figures he doesnt have to prove that he cares for you after 3 yrs =/?
and all that "sweet things" stuff usually begins at the begining of a relationship, kind of like when you get married. But it starts to to whither away when you guys spend more time together, not because he doesnt care for you anymore, its just that... sometimes guys feel it doesnt need to be said anymore, its unspoken, or that you should know by now and usually your more secure also, so yeah.
its kinda like when you meet a friend for the first time. you might feel the need to make conversation, get to know the person, and all, but soon when you guys start to be best friends,and you dont feel the pressure to have to make conversation anymore, you can sit in a room with your best friend and watch TV and not say a word to eachother and it wouldnt even be awkward. so yeah, thats how it kinda is in a relationship for guys... but for girls, they want the sweet stuff said to them all the time. but one question, does your bf always get sweet things said to him? because usually when a sweet thing is said to one person, they will return something sweet back. so yeah! hope i help a little and made sense
