What do I do?

gills • 17 year old gal from the UK
So my boyfriend and I came from different social circles and now I'm in his circle as i basically lost everyone else in dating him. But now he doesn't get invited out with his friends much and he spends most of what little free time he has with me. Do you think it's my fault? Should I push him to spend more time with them? It's just that I barely see him out of school as it is so I don't want to end up not seeing him at all. In a way, I kind of don't want to always be his number one priority... Does that make sense?
