Should I delete him off everything?

[Cece]

I met this guy in the summer and we became friends. He's two years older than me. A few months back he said he liked me, and we went to the movies. The date was pretty bad. He tries to walk around like a gangster and kept trying to kiss me by telling me I had something on my face.. when he did kiss me, it lasted for a few seconds and It just didn't feel right. He kept bringing up us dating and I told him it wouldn't work out. He wouldn't let it go for a week. He finally accepted it but continued to message me nightly telling me how he missed me, despite the fact that I ignored all of the messages. He still posts things on websites like "I wish we could have worked out" and "I miss our conversations". It has been 4 months and I'm starting to get a little weirded out. The other night someone anonymously messaged me and asked if I missed anyone, and I know it was him. I know it sounds bitchy but the reality is that he's a nice guy and I appreciated his friendship, but he isn't going anywhere in life. He's 19, lives with his parents, and did not pursue higher education. He smokes weed everyday and claimed that "we hooked up several times" when he only pecked me on the lips. I'm just annoyed by this whole situation, and debating on deleting him from social media sites. I'm going away to school next year and won't communicate with his again- so what's the point? What do you think?
