Is it bad to get too comfortable with your partner and go to sleep on them? (long post)

I (28F) am in a long term relationship with my partner (29M). He has always been amazing in every way, he is so kind and understanding, and is the best partner a girl could ask for. We are now 7 years in together and honestly it feels like the honeymoon phase never really ends. We’ve never fought, and I’ve always felt like he loves and respects me so much. We are pretty much best friends too, so the relationship feels really healthy and loving.<br><br>However, I’ve noticed over the last couple of years that I’ve been sleeping on him a lot. He’ll give me a hug goodnight and I’ll just kinda pass out, and the next thing I know he’s gone into work and I’ve been asleep for hours. He always seems to love this and never complains or says anything about it. But I’ve thought about it and I feel like he deserves so much better. He always goes out of his way to make me happy, and I’ve been falling short of that back.<br><br>The other day I woke up and he was laying in bed with me and he said “I know you’ve been sleeping on me a lot, but it’s actually really nice. It makes me feel safe to know that you feel that comfortable with me.” I got really embarrassed and didn’t say much and I know he could tell because I could feel his arms around me get a little tighter and he kissed the side of my head. So I guess that’s my question, is it okay to sleep on your partner a lot? I know I shouldn’t be taking him for granted but it feels like he actually likes that I do it.
