Parent problems ??

Ever since i have gotten in a relationship with my bf my parents have been way more strict. And my mom doesnt even like him. She may seem like she does but i know she doesnt. And my parents all of a sudden think i have an attitude because who knows what and my dad asked me if i needed a therapist. It just makes me a bit annoyed when they automatically assume i have an attutide when i dont. There are just times when i just dont want to talk i just want time to myself. To just think to myself thats all. And now my mom says im pissing her off and she'll make us not see each other no more. Does anyone have the same problem or going through the same thing as me? I really do think this is the only place i can speak and get advice.
