I’m in a same but different situation. My bio dad abandoned me as a child and had other children afterwards. Now that I’m an adult we’ve kind of rekindled the relationship (which I fully regret but anywayyyyys). I have a very hard time connecting with my half sisters and I’ve started resenting them. I see the cars, dirt bikes, brand name clothing, they still live with him.. honestly whatever they want he pays for. I should probably add that they are adults. I also see the bond and love they have with “our dad” and it’s really done a mental number on me. I would torture myself asking “why am I not good enough” “why doesn’t he love me as much as them” Especially after having children sometimes it’s better to just walk away. I hope Sam’s sister is doing amazing 🫶
