My partner and I lived together for 8 years and although I didn’t feel I was the marrying type I thought it was the the thing to do (and I did love him). Too be fair he had a bit of a reputation and my sister was always jealous. A few days before I was due to get married I found out my sister had been sleeping with him which as an after thought made sense as she thought I disrespected him. But long story short, they were not married long and 10 years later me and him (I know I am a fool) are back together and have been for 16 years and she is no longer part of my life. My issue which I please need advice on is, her daughter who was the light of my life and then taken away from me refers to my fella as dad but has not made any contact for 10 years and when sh3 got married (1st wedding booked for Caribbean no invite) and wedding Booked register office but blamed lockdown rules, which is fair enough but if you can’t have the person you refer to as dad then he is not dad, her marriage has now split up and is phoning dad, I will always help them but my head is mangled, please give some advice
