<human>: My boyfriend and I have been together about a year. Everything has been fine up until about a week ago. He hasn't been acting the same, has seemed like he isn't happy to see me, and hasn't been as affectionate. I've confronted him with my feelings and all three times he's nonchalantly denied them.

This has lead me to believe that i'm overreacting for some reason, and that he's just more comfortable with me and i'm just insecure. I wouldn't think he would be the type to dump me out of the blue, but unfortunately it's happened to be in the past and i'm terrified of it happening again.

I'm usually right about these 'hunches' that I have. I'm not sure if I should have a serious conversation with him about it and risk looking crazy, insecure, etc. or I should just wait and see if things get better or he brings it up himself... what do I do?! I don't want to ruin my relationship but I don't want to be a sitting duck either...

Can you give me a shortened version of the text?
<bot>: My boyfriend of a year seems distant but denies it when I ask him. I'm worried i'm acting crazy or that i'm totally right and am not sure what do to next.
