In all honesty, ask her to explain what she means IN DETAIL about those responses and go from there. Make her use her words
Hell nah OP don’t do this shyt. It best to immediately after she say that agree and disappear. Guarantee it will turn the tables and have her doubting her feelings because guys don’t do that. They try and fight for it and women aren’t use to a dude saying “thanks I was thinking the same thing

“ and immediately falling off the face of the earth.
Don’t argue, fight, plead, convince or any of tha bullshyt that make you look like a sucka
You won’t ever get a straight answer and she will spit a bunch of bullshyt at you to soothe your pride. The only thing that matters is ACTIONS and I’m sure by the time she’s telling you some bullshyt like this her actions have already started/been showing that you not the one.
If it ain’t a hell yes it’s a NO. In my 20+ years of dealings any time a woman said those phrases to me she was still emotionally stuck on another guy.
Any time a woman start acting funny and she’s not your LADY the answer is always do nothing.
