Desperately need advice
I met an ex partner of mine eight years ago and we got back together. She had a child of ten at the time, and she informed me that I may be the father of this child, from when we dated years earlier. After months of agonising and debating what to do, we told her that I may be her father and that we would take a DNA test and move forward from there. The daughter was set against the DNA test so one was never taken; we got on fine from then and had a happy time together. Then two years ago when my partners daughter hit 16, she accused me of being a sick twisted man for entering her life and pretending to be her father. I explained to her that I wanted a DNA test, and that her mother and I had agonised over what to do for the best and Yes we probably shouldn’t have said a word. Things calmed down and we started to get back to how things were; recently, my partners’ daughter has said the vilest and disgusting things to me, claiming I am vile, vulgar, sick and twisted for wanting to ruin her life.
She thinks I came along and ruined her life out of some sort of spite or twisted pleasure. She has started telling her mother that I am seeing other woman (which I am not) and that she has seen me with other women (which she hasn’t). She asked her mother end her relationship with me, when se refused she stopped talking to her mother after telling her she had no respect for her anymore.
I seriously do not know what to do; I love my partner dearly and don’t want to end our relationship. I love my partners’ daughter and don’t want her upset. Should I walk away from my partner so her daughter is happy or do I ride out the storm and hope she claims down one day? I seriously do not know what to do for the best
