Been seeing her a few months now. Chemistry is off the charts in every way. Legit one of the only women I've ever dated who I legitimately enjoy hanging out with beyond sex. Problem is, I'm falling for her. Big time. Like it's difficult for me to talk to other women because I have such strong feelings for her and only want to see her. I don't know if she's talking to anyone else, but I want her to myself at this point--I want to be exclusive. Is there any way for me to tell her I want us to be exclusive without losing "frame" or whatever?
