Your W just told you her Love Language dude!!! She's like me...Quality Time....you just got yourself a HUGE clue as to what to do to get her to respond to you.
Also....from what you said, it sounds to me like you need to do some validating when she's talking to you, in order to make her feel understood and acknowledged. You have two things right there that can be excellent tools in turning your sitch around. Validation and Quality Time.
Now, when your W says "time with you", do you know what she means? For some people quality time could be doing home improvement around the house....for others, like myself, it's time one-on-one together....talking, snuggling, playing backgammon over a glass of wine...sitting on our front porch enjoying the view and chatting about the day...stuff like that. She's opened the door for you to ask some questions like "honey, when you say "time with me" are there any things in particular you enjoy doing with me that we haven't been doing lately...or are you talking about just spending time together in the evenings talking about our days?
Sooooo....it's possible your W has not been having her needs met in the way she needs them met, because of course you didn't know what those needs were. Because of that...she's thinking he's not meeting my needs, but he's going on and on about me meeting his....see the vicious cycle here? It takes communication, and loooooots of it
