Long distance- should I break it off?

So I've been seeing a guy since about October. He doesn't actually go to uni and he's currently just gone offshore. He's been gone less than a week.
Right before he left, we on and off fought. I wanted to break up with him at points but then couldn't do it as I liked him too much.
Thing is, he's very insecure and needs constant affection and reassurance over text. I'm busy with work and my family, especially now it's xmas. I just feel like it's a chore sometimes and more so, the things he says I find SO (!!!) cringey and weird.
Thing is, I can't just end it. We have plans to meet really soon. My family love him. Most importantly, he's SO fragile. Like last time we almost broke up he kept crying and begging which made me bend.
I know talking like this about him probably means we should break up as I clearly don't like him as much as he likes me, but I also don't want to. I just hate the constant phone calls and texts and need for attention, it's too much for me.

Do I end it? Am I just being really immature?
