I am talking to 2 girls. Girl A is the one I am really into. She is the hottest and we have the most in common. Girl B is not bad at all and absolutely down to fuck. I want both as plates.

Now. I made plans to go out with girl A Saturday night. Texted her last night to make sure we are still on and 2 and a half hours later I get "As far as I know lol." Not really the "hell yes" I was looking for. I realize that interest is lower with this one but could be raised on the date.

Girl B texted last night saying she is free Saturday. I said maybe it will work out where we can hang out. She sends me a nude and says hope so. Did not tell her I already have plans, but didnt commit.

Since I have already made plans with A I will honor them, but realize I am likely her backup and she will likely flake. Any advice how to handle? Or am I doing this right?
