Ok this is a complicated one so bear with me… my mum and dad had a very toxic relationship and split when I was 11 because my mum had an affair. Shortly after her boyfriend moved in and I was miserable with them. My dad moved on and met a lovely girlfriend and I got on brilliant with her daughter. I unfortunately couldn’t live with them because they lived 3 hours away and it was too far from my school but my dad promised if I finished school I could move in with him. But when I was 16 we were all absolutely blindsided when it came out my mum and dad were having an affair with each other behind their new parents back, resulting in a huge fallout and them getting back together, suddenly putting on a united front and acting like the past 5 years never happened. I was forbidden from contacting my dads ex or her daughter. Back to the present, 12 years later and my DH and I have just booked a holiday to Rome. The last time I was in rome was with my dad, his ex and her daughter and I have lovely memories of it. I looked her up on SM and she has a private account. I sent a brief message saying “hope you don’t mind me reaching out, I’ve always wondered how you and your mum are over the years, hope you’s are keeping well” type thing. But now I wonder if I shouldn’t have done it? I’d love to get in touch, after all we got on great and what happened was through no fault of any of ours, but what if she thinks it’s weird after all this time? Was I BU to message ?
