What is this some kind of ual deviant plan?

I slept with this guy...turns out he was a player and cheating on his fiancee. Well she and him are both loony . She's dying of cancer and he's in and out of jail . Well when we first met she was cool with me..then got mad that I was still occasionally sleeping with him cus HE SAID they were no longer together. Then she and I became cool again cuz she knows he lied to me and what not. Well now he is in jail and she and I have been kinda pulling together for him (im his friend and she is his girl). The other night tho she and I went out for drinks and we kissed and made out a little! My FIRST EXPERIENCE lol. But...does she really like me like she acts like (staring at me, touching me, saying im beautiful AND buying me new clothes and makeup) or is is a plan to KEEP me away from her man when he gets out of jail? hmmmm
