Clingy friend won’t stop texting?

Hey guys, so I have a new friend I met at work he’s a good 10 years older than me, but I believe he had a hard life doesn’t seem to have a lot of friends. He got fired from the job, but He texts me constantly ! I’ve said twice stuff like ‘I’ll text you next week’ and he never listens he will text the next day and all weekend, it stresses me out. Honestly, it has put me completely off him! I have a life a boyfriend a small business along with my full time job! As well as this, if I was to answer my texts go blue straight away as if he is sitting there waiting for me to respond! We got along great at work for 8 months, but now I feel guilty that I am feeling he is strange and I want away from him :( I don’t sit on my phone all day not even to my closest friends! Now when I see texts I just get angry! Any advice would help!! Thanks all :)

He’s definilty lonely, but to rely on me a girl in a relationship doing a million others things has taken it’s toll on me. I know I sound horrible but do I need to stay friends just because he’s lonely? I am not going to lie he wanted to go for lunch a few days ago and I really didn’t want to see him. I wish him well but I don’t honestly want to hang out anymore I think he’s pushed me away with not respecting my boundaries in texting
