I had surgery friend wants updates but makes it a point to be friends with people that don’t like me (don’t want my business out)

What do I do? Do I tell them I don’t trust them because of this and want to give them an update but I’m like… I don’t want them to know. Do I cut them off? I made it a point before, but they seem to just keep them around. I know if it keeps bothering me I need to make the choice because they dont seem to mind playing both teams. They have been very hostile to me & I’m very serious about the people i let close to me. I care about my friend but this is keeping me from fully trusting them. Do I have a talk in person? Do I text them I’m not comfortable bc I dont want them to know my business? I’m stuck
