Overstaying your welcome 🙄

Br

I have a friend that is single and likes to come over but doesn't know when to leave! My boyfriend works third shift and I'm always up super early to greet him when he's off and spend time until we both go back to sleep. My friend is single and doesn't know when it's her cue 🙄 she'll lie in our bed or wherever. I've tried to tell her once before like this is our quality time when the kids are sleep and he's winding down from work and she took offense. I know it's kind of irritating for him to come home and she's still here just as much as I'd like for her to be gone when he gets here bc I look forward to spending that time alone with my man. How do I get this friend to get a little less comfortable in our home?
