Questions: Relationships

I am not getting the benefits of being an adult. Just about all my peers are married, many with kids. Meanwhile, I never even had a real girlfriend. People are moving on in life while I am not progressing. I also still live at home under my mother's wing. I am hardly getting by. I have bills now and people have higher expectations of me. I haven't had sex in 8 years since I lost my virginity. Life sucks.

School started back up and my girlfriend lately has been declining my calls a lot even outside of class hours. She often goes the whole morning and afternoon without sending me a single message and then I call and she just hits decline and sends me nothing still until late at night. She said she would send me a small quick text to let me know what's going on as for why she declined the call, but she doesn't do that. I try to be very understanding if she is really busy but it doesn't seem like it should be so hard to send me a small message. I have no idea if i'm being too needy or not. one of my friends said she would freak out and start spam calling if her boyfriend did that. I was curious what more people think.

The contrasting difference between their skin tones makes it look more interesting and sexy/attractive or sort of weird and unappealing?
