Is my gf living with me?

My gf and I have been together for 5 months. I’m 21 and she’s 23, I live with my family and she lives in her car and sometimes at her parents house. We’re in the process of trying to get better jobs to get an apartment. She’s been over my house every night since our 2 month anniversary. I know we jumped in quick with spending a lot of time together but I enjoy her company, but my mom is worried about me having her over all the time, she’s even getting jealous that I spend so much time with her so often. Which I completely understand and I make time for my mom now but she still thinks her being here is starting to become too much and I agree with her. My other options with my gf are sleeping in her car or well….being at my house which quite frankly stresses me out because we’re here EVERY NIGHT and it’s taking a toll on my mental health and it’s definitely taken a toll on our sex life. She considers herself “homeless” because she doesn’t feel comfortable in her own home with her parents, they’ve been abusive towards her when she was younger but now that they’re older they’re trying to make amends but understandably my gf wants to stay away. It’s gotten more intense with her being here, I do her laundry, I cook her food cause she’s too scared to cook herself food in my house which I understand, knowing how my mom feels. She’s been showering here and quite honestly it feels like she lives here. The only difference is we both work so when I’m gone she’s gone but when I’m home she always here and it’s becoming a-lot. How do I go about this?
