Relationships advice, I guess?

So, here’s the thing that’s been heavy on me these last weeks. My girlfriend of three months and I are polar opposites. She is and introvert and has an extremely hard time being around people, even her closest friends, she says that quarantine has been a blessing for her. People drain her from her energy in a matter of seconds. She has her own severe trauma and has a hard time opening up to people. More than than, she says she never does. I, on the other hand, can’t imagine myself being disconnected from people. I have BPD (I’m stating this, so you understand the severity) so to me these three months have felt more like a year, when for her it has felt way less. The point is, she recently said that everything is good in itself but she can’t help thinking that she’s way more comfortable being alone rather than with anyone else, and that includes me. I didn’t answer, because it felt like I’ve been stabbed and that it means it close to being over. So, I wanted to maybe get some advice if anyone has been in a similar situation or something. Does it really mean that nothing can work out or is it just a thing that we have to come around and learn to be comfortable with?
