WAW having an A but she denies it

[shodan]

We both work and have shared bank acct and one shared Amex card. Never been an issue until now. We make an equal amount of money.

Another question.... I bet she comes home this weekend and asks for a separation. She won't admit to the A but will say she needs space and time to think. She'd likely will say that because I don't trust her proves that we need to separate. Should I agree to the separation? I assume yes.
