Male (25) had sex with female (29) and she revealed to me last night that she's married and has a 10 year old son. I am so confused on what to do?

Okay so I met this girl on a dating site about a month ago. we conversated for 4 days and most of the convo was very sexual. we got to know each other a little, she's a nurse. She told me she was single and so forth. Anyways we had sex three times the first time we met and have been constantly texting since then. she will often remind me how good the sex was which is weird because no matter what day I text her she will always bring that up. Anyways we were supposed to hang out yesterday and she never showed up. She also bailed out on me last week. But, she will still constantly text me with naked pics and tease me. Anyways, so last night I straight up confronted her and she told me she was married and had a 10 year old son. She send me pics of her wedding day, her son, and a family pic of her with her husband and son. I am so shook like I don't how to feel about this? She tells me we can keep it on the low, and the reason why she's sleeping with me and whoever else is because she's tired of her marriage and also thinks her husband (38) is unfaithful. she's also made a comment saying "your the first colored person I have slept with and honestly you make me wanna explore more races, because you fucked me way better than any white man ever has" (i am not black btw). So, yeah lol idk im just shook rn.
