Finished up my third date/hangout with this chick and it seems like shes fallen for me. Told me she yearns for me when im away and that it would bother her if i was dating somebody else but admitted shes not my girlfriend and i can go do what i want. I do like this girl and feel like we connect emotionally. But eventually she does something that reminds me shes a woman. Posting a (not sexual) thirst trap on ig story after i havent been responding much. Im going to see her and most likely have sex with her for the first time tomorrow, and have her stay the night, but also have another girl asking if i want to hang out this weekend for our second date. I didnt like her that much but i would definitely go if it werent for this other girl. Should i go for both?

How would she react when she eventually finds out i went out with another girl after i seem to be serious with her?
