I am caretaker for my mom, stepdad, husband and my mentally disabled little sister. In the last few months, my stepdad has been behaving overtly, well, "lover-ish" towards me. He calls repeatedly throughout the day. He gets upset if I need to do things with my husband. He tries to hold my hand constantly, but lets go and acts guilty when my mom walks in the room. When i go to kiss him goodbye, he grabs my waist and tries to get a lip lock (I have always kissed his forehead). There are too many other weird incidences to mention, but it seems to be getting worse. I have tried to tell him he is being inappropriate towards me and making me uncomfortable, but he starts crying and threatening to kill himself if I don't spend more time with him. I admit to using my own health issues as an excuse to avoid him, but he just gets more desperate and clingy when I do go over. My mother is toxic under the best of circumstances, but has lately upped her viciousness in response to his neediness.
My stepdad and have always been close, good friends ever since he came into our lives when I was 13. I have always felt safe with my stepdad. His recent behaviors are making me want to run away and hide. It is breaking my heart to lose my mentor and best friend this way. What the hell do I do? Is this from his medication (no changes in months)' damage from the stroke 2 years ago or some new, fresh hell?
