<human>: Can you succinctly summarize the text in 1-3 sentences?

Hey all, I was hoping I could get some opinions and advice on the current situation i'm in. I appreciate it in advance.

A year ago I was able to get a job in retail. I'm now meeting tons of people and making great friends, and even a boyfriend! But the problem is my mother doesn't approve of me being with him and I'm starting to feel depressed. 

The reason this is, is because he has cut scars on his arm. He had a very dark past, and it is behind him now. But on one particular night at 3am, a family member of his passed away very suddenly and he called me telling me how he felt the urge to start cutting again. I was concerned as anyone would be so I told him to come to my house so I could help him. She found out the next day and I ended up telling her the situation, she now believes hes dangerous and a threat to me. That "if he can hurt himself whats stopping him from hurting you". I have not been able to be with him outside of work for the last 2 months now and it is straining on our relationship. The truth is I've been lying to her by saying work called me in a couple hours early, so that she will drop me off, and he will pick me up from there to spend a couple hours with me. I feel extremely guilty for lying to her, and completely paranoid when I'm with him.

I've had tons of people tell me "You're 20, she can't tell you what to do" But it is not like that at all. Sure, I *can* go out, be with him and do whatever I want, but at the cost of her trust and respect for me, and possibly our relationship. I respect her too much to ruin our relationship, she is the only family I have and have ever known. She is just very stubborn and the kind of person who is extremely difficult to talk to and reason with. I don't know what to do or say to her.
<bot>: my mom thinks my boyfriend is dangerous and a threat to me because he used to cut himself. Haven't been able to spend time with him in 2 months
