I've been in an LTR going on a 1 1/2 yrs. We've had our ups and downs but the last few weeks she has been withdrawing.

Hard to put my finger on it exactly but I feel it... she's not as warm or affectionate, kissing her is different, etc.

Last week instead of the usual marathon sex session (she's never refused sex and normally is into it every time we get together) she slept on the couch while I crashed in her bed. She said I was snoring so I say wtf and forgot it.

Last night she again feels distant and argumentative and sleeps on the couch.

So when I wake up early I just get dressed and start to leave. She woke up and started to protest but I said nothing and kept walking.

I have a gut feeling this is going to flame out..or already has.

I think I did the right thing by walking.. what to do now?
