End a friendship from needy friend?

Hi guys

I have a friend who is only friends with me maybe 8 months. He was contacting me too much so I had to ask him to stop (nicely) but he is older and I think lonely. If I am extremely honest I don’t want to be friends :( but I am having trouble cutting him off. He text me even if I tell him wait for me to text him. He asked me to meet up with him and I genuinely do not want to I feel guilty but I can’t be friends out of guilt it’s not fair to him or me. I kind of hoped he got the hint when I asked him to stop texting but he didn’t I think he is so lonely he doesn’t care what he looks like.
I even stopped going on to my WhatsApp as I know he stalks my status I text my friends on normal texting.
I am in a relationship a good 10 years younger than him and I just don’t want him as a friend. Please help

The fact I asked him not to text me wait for me to text me then a week later he texts again just makes me feel he’s strange as I would never text someone who would say that I’d get the hint
