@Taliban Istikhara for what Hadhrat? To me this does not seem to be a situation requiring Istikhara. @Sister Muslimah79 Please sister exercise your tawakkul in Allah(SWT). Make only moderate amount of inquiry about his activities-then exercise your own judgment and restraint. Pay enough attention to your personal appearance (good dressing, personal hygiene and make-up) and fitness-join a female gym if it is feasible other wise get some exercise equipment at home. If he asks about your new hobby then just tell him that it is for him-no appeasement, no pretension. And make lots of duas, lots of them. May Allah(SWT) return his focus to you and may He make him more responsible. Wassalam
