ran out of this go talk about

me and my boyfriend have been together for almost 5 years. we are next door neighbors I've known him for 14 years. we spend most of our time together from 5 to 9 30 p.m everyday I don't mind at all spending time with him I enjoy his company. there's has been times I've told him if he wants his space to do things he can but he doesnt. most of the time he does go out and play tennis and I don't mind it. but I ran out of things to talk about we don't talk much and i was wondering if any one can help me and give me some advice ?
