My boyfriend wants a break and I don’t understand

So my boyfriend wants a break for 4 weeks after being together for 9months and I don’t understand why I’m giving him the break but I honestly don’t know what to do because he wants this break so he can see if he wants to be in this relationship and I give him all the space he wants and I am a overprotective person but I keep it to myself I let him go over to one of his female friends house to smoke and I let him go out with his boys so I just don’t understand
