I've had rituals done from Tina and I have a couple virtuals coming can I still burn Layla's candles hello deadly attraction or wait?

Yup but if you had never done unhex or any cleansing that was first with Chaela.

well now since you did work if you unhex before halo.. or whichever, you will have to be careful in your chants and specific to not accidentally erase the work you got done with the rituals with Tina since unhex ritual/candle can easily remove any majick. you could say remove all evil or negative majick works someone put on me/him/our relationship..
