I get my title may seem petty, but taking it at face value, I want to know the ideal way through "TRP" lens to approach asking my LTR to sleep over without coming off needy.

I do my own thing, have hobbies, lift 5-6 days a week, text her fairly infrequently / unpredictably, etc, but I do enjoy when my LTR sleeps over. She gives me massages, she cooks for me, sex is amazing, etc. She normally sleeps over 1 or 2 times a week max (sometimes less, never more). We both work 50 hours a week - so not a crazy amount of free time - I get that.

Should I never bring this up again without her first initiating? I've asked earlier yesterday, and she was non-commital to a day I suggested.

Thanks.
