College student doesn’t want to come home for summer

I have a homebody, but once she hit campus we haven’t heard much from her. I know I should take it as a job well done, but this empty nest thing is real. I still miss her terribly, but the alternative was her being too dependent on us emotionally and socially, or worse me being dependent on her. I’m trying to encourage her to find a job away from home to keep her in a social environment. We live in a retirement/vacation town, so most who live here permanently are 65+, not great for a college kid. She did research last summer, but because of covid it was all remote from home. She could’ve done research again this summer, but it’s still virtual from home. I don’t want her to spend another summer working in this house. At this point I just want her to be with people her age. Growing up in the NE, many college kids lived and worked on the jersey or MD shores for the summer. We saw our parents when they came to the beach for a weekend.
We did make it clear that her job needs to cover her living/personal expenses and hopefully more. She banked all her money from past jobs, so she has enough to cover personal expenses for the next couple years of college. I personally wouldn’t contribute extra money during the school year; maybe he can also get a side hustle job over the summer to bank enough to cover expenses for the upcoming school year?
