Need Advice about Online Friend

Hi, I'll try to make this short.

So ive got an online guy friend (I'm female 19, he's 27) and we've been talking for about three weeks, we found each other through 7cups and switched to calling, texting, and sending audios instead. We used to talk pretty much every day until I realized that I was getting tired of spending every day talking to him. He was always showering me in compliments and telling me how I am the best part of his day (all he does is go to work and come home, lives with his parents, single, very introverted) and he's a super nice and caring guy but since we talked every day I realized that I was ignoring my own life while spending time on my phone instead of going out and doing stuff.

I just got home yesterday from college for summer break and I had told him a few days before that that I needed some me time off my phone. then I called him on Tuesday and we talked before bed, and the following morning. I also talked to him briefly this morning (may 4th). earlier tonight he sent me a text saying how he misses our daily talks and it had him feeling "some type of way."

I know he's a lonely person, doesn't have many friends but with the constant praise directed towards me and us always talking i'm at the point where he's so clingy I feel the urge to just stop talking to him. I cant handle clingy friends, one of my pet peeves is when my friends text me a lot on the phone or get super attached.

I guess im just looking for advice. I told him that I cant talk as much as we used to because its summer and I have to spend time with family and do other things, but I would still keep in touch. I was hoping that by distancing a little bit he might try and find others In his own city and environment to meet and hang out with instead but I dont think thatll happen to be honest. I guess im just afraid he's becoming too attached, cause it makes me feel guilty that I dont call him as much even though ive got to live my own life.
