Complicated relationship?

Confusing relationship

I met this girl in my law school (Vanessa) about 8 months ago. The first night we went out to dinner and she spent the night but we didn’t have sex. Fast forward we have been out countless times together for drinks, dinner, bars, and sometimes she just comes over and we have drinks at my place and don’t even go out. She always ends up spending the night and sometimes we spend the next day together.

She has two sisters who both met me and like me a lot I’ve even spent the night at her sisters house with the girl I’m talking about (Vanessa) a few times made out with her on her sisters couch etc. Anyway, my predicament is we have been seeing each other for months now and have not had sex. There’s been a couple times where we almost did but it just didn’t happen. We’ve only made out, dry pounding, and I’ve sucked on her breasts but that’s the farthest we’ve gone. She’s 28 and I’m 25. She sees me as player type guy I guess because I’m very sociable at the law school talk with everyone, very charismatic, and I’m always going out with different girls she sees it on my snap story all the time. I’ve met her parents too been over to her house and she has met my mom also.

I’m confused because I genuinely like this girl but I get the feeling that I’m being used as some proxy boyfriend or emotional dildo. I have a fair amount of experience with girls and it’s never taken this long to have sex with a girl. She’s not very religious or a virgin bc we’ve talked about our past sexual endeavors. At first this didn’t bother me that much because I figured it would happen eventually. However, it’s been 8 months and we haven’t had sex and it’s just making out, dry pounding her in my bed, cuddling but never sex. Every time I escalate she moves my hand or indicates to stop. I’m very sociable and can get other girls and she knows that so she doesn’t view me as this pansy desperate guy but I’m confused because I like this girl a lot but I feel like she is friend zoning me in a way or using me as an emotional crutch I guess even though we kind of hook up. What do you guys think about this? Any advice appreciated.
