If you wanted to send them gifts bc you want them to have those gifts that’s fine but you honestly shouldn’t have expected a response from her as it’s obvious she doesn’t want to talk to you at the moment.

All she’s thinking is that you’re only sending gifts in order to guilt trip her into talking to you. Which it seems exactly what you’re doing since you seem annoyed you never got a “Thank You”. Honestly I’m not on speaking terms w one family members and he tried this BS and I never opened the gifts. I never asked him to send or give me a gift he just decided to do it. I don’t owe him anything and those gifts are still unused and he knew I didn’t want anything to do with him and hadn’t spoken to him in months why did he assume I would suddenly be so grateful bc he sent me a gift?

It’s better to just leave her alone bc all you’re doing is annoying her. She’ll come around eventually when she’s ready to talk. Give her some time to breathe and access the situation, she’ll come around when she’s ready you can’t force anything right now bc you’ll regret it and she’ll end up saying things that you will not want to hear and will only hurt you.
