My(32M) gf(30F) has no support beyond me. What to do?

Hello, TLDR: gf has no friends

I have been with my girlfriend for 5 and a half years. I am quite introverted, but I have developed enough social skills to make friends if I have the energy to do so. She is less introverted than me, but more anxious in social situations. I believe this is the heart of the issue; her minimum amount of social interaction is higher than my maximum. So either I give up my solitude time and become a worse version of myself (tired, grumpy, passively neglecting her even though we are spending time together) or I sacrifice her social/mental health by actively neglecting her.

I would like for her to make friends, but I know that is much easier said than done. Maybe a therapist would help? At the very least, she would have someone to talk to other than me about the times when I’m being a wiener. It is very difficult to be the one listening and the person she needs to vent about.

I need to spend time by myself. She needs not to. How do?
