Relationship advice

I want to know if I should be given a chance or not. Please help. I was with this guy who was really good to me for a few months for summer 2019 and abruptly ghosted him because of my own life issues, and for the next year and a half barely progressed in life, hanging around the wrong crowd and being useless. Ended up getting an abortion after being with someone for 4 months and then continued to hang around the wrong crowd for the next few months. December 2020 the great guy and I reconnected and ever since are in a relationship. But not short of ups and downs, because of my past he’s unable to accept me fully or even want to do sexual things with me. Pls help.
