Everything was going completely fine, she is the one who chased me before we go in reliationship, lot of sex, she initiate all the conv on text, she is always available etc

She had her period few days ago and she started to act bitchy, very distant, not initiating anything, not available, for me this is a complete disrespect, period or not ...

So i basically soft next her and no contact for 3 days, and now she initiate text

Her : Hey

Me : Hey

Her : I'm not very sure about us, i don't know how to explain

Not sure how i should answer ? It's a girl i met few months ago, she isn't my type so i don't care much to be honest, but sex was pretty good with her

Should i just answer "I feel the same thing, it won't work between us" or should i text a little to know if it's a test ?
