I'm not happy. But so confused!

Normally I'd say to someone who says those three words: "I'm not happy" that there's your answer... break up with them. But I don't see it like that.

I really love my boyfriend. Really do. But there's times where I feel like I'm (scum?) to him It's like he switches and when he speaks to me, well you wouldn't even speak to 'friends' like that. It's without respect. Now, I ain't asking for a lot... but I think 'respect' is vital in any relationship, be it loving, friendship or acquaintance. It's as though he thnks because we've been together for a good 2 and half to 3 years that all that goes out of the window.

I just want things to be good it really hurts when he's like that so of course I get upset and recently it makes me angry even because he's flipping clueless even though I've spoken about it. But then it gets turned on me because I'm upset and angry.

I can't even really think any more this situation has literally just happened and I feel alone and didn't have anyone to talk to so figured I could write on here.
