My father Is Naming My Half Sibling Exactly The Same Name As Me. Is It My Obligation To Solve This issue?.

I actually (18f) found out a three months ago that my dad (54m) is having another kid along with my stepmom Laura (33f).

This all occurred when I was staying at our dad' s since I just visit him twice a month. Laura and my dad sitting me down and told me they were expecting, which I didn' t think much of given that I' ve never already been close with Laura. I asked if they' d thought of any names plus Laura said she would tell me when they found out the gender of the baby.

About two months later when I had been on Skype with my father, he told me that they had been expecting a girl. I wasn' t exited but We wasn' t unhappy for them either, it' s one among those things I wasn' t really sure how I experienced. I asked if they' d picked a title and Laura interrupted and said they' d be naming her " Lilly". (my name is " Lilianna" and I go by Lilly for short)

I guess our face must have said it all and my dad started stating " it' s only a name, two people in one family members can have the same name" plus " Lilly and Lillianna are completely different names".

After that I just ended the phone call and didn' t visit my dad that weekend. I' ve talked to my mom about it and she agrees it' s weird of my father to be okay with this and understands why I' m be upset with this. I possess since cut contact with my dad and haven' t answered any of his texts or calls for a few weeks.

Laura has tried to get in touch with myself through FB, saying that I' ll always be my dad' s first child plus he' d never substitute me. So why did these people pick exactly the same name because mine?. My grandma (dad' s mom) is blaming Laura for this drama and it is suggesting I should contact my dad to sort this event out. My dad wasn' capital t there for me during my more youthful years so this feels like he' s having a new baby to replace what he missed.

Could it be my responsibility to type this out when we have not been close and he' s basically trying to replace me with a new baby?.

Tldr Dad is identifying my half sister the same name as me and family are saying its not a big deal and it' ersus just a name. I feel changed and don' t wish to contact my dad. Grandma states I should.

For everyone asking, I use my mom' s last-name since my dad left while i was two months old and didn' t get on contact with me until I was 13 yrs old, just before he or she married Laura. He by no means married my mom so I got her last name.
