What is this some kind of sexual 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 LESBIAN 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
