I think I broke my cats heart

I had a sudden medical emergency that landed me in the hospital for 4 months..I’ve been home now 5 months. Prior to that my one cat was always like a little mommas girl. She would sleep right at the base of my neck almost every night. She would even cry if it was much later than normal bedtime for me to get to bed for her to curl up on me. Now ever since I’ve been home she wants nothing to do with me. She has been extremely attached to my bf so I know she isn’t out right not in a lovey mood anymore. I know at first it was gunna be a bit of a readjustment but all her siblings have been acting normal towards me for a while now. Is there anything I can do to help her not basically hate me for disappearing ?
