At least you recognise the pattern. Have you ever had counselling? It would really help to understand where this all comes from. What you feel you need from these relationships. We are drawn to what feels familiar and maybe it’s far too familiar for you. Give yourself some time before dating again. Time to find your own needs and hobbies and things solely for you. I’m dating myself, it’s great. I buy myself things I like, I see movies I like, I have meals and go places I like. Maybe eventually someone will fit in my life but I’m not fitting into someone else’s life again.
