We have been dating for 2 years now and have been doing not so long distance for just about a year. For the past few months she's been very distant and rude to me. Won't text me even if she has time. Won't reply to my good morning or Good night texts. Will only call when she is free and won't pick up 70% of my calls. Lately she had fever and I asked her in the morning If she was okay and said she was feeling a bit unwell and then when I asked her at night she lashed out and told me to shut the fuck up as she won't feel better if I keep asking.

She is brutally honest with me and doesn't seem to handle honesty very well herself. Example: I was very excited to wear my new shoes and she tells me to change em as they didn't go well with the outfit and yeah she was right. But when I told her her top didn't match her pants, she again told me to shut the fuck up and didn't speak to me for hours.

She wants to marry me but doesn't want my last name which is absolutely fine but she wouldn't want our kids to have any mention of my last name as well.

What do I do?
