Relationship issues!

Hi girls some advice please! So I've been having a lot of problems going on at home and dealing with depression etc and so I've been spending weekends at my boyfriends to get away. But every weekend I've been at his, he's had his friends round at least 1 night! Now usually I don't mind but it has been every weekend for the past 4 weeks now, and I'm meant to be going to his tomorrow.. but apparently he's now seeing his friends (the same ones he's been seeing all week and weekends!). He knows I don't like being at home at the minute and that I'm struggling with things - do you think it's bad for me to still ask him if I can go and stay in his for the weekend? I mean he's spent time with his friends EVERY weekend. X
