Is he getting into the part of the relationship where he needs his space? answers please?

My b/f and I have been together for 8 months. We get along great and we do stuff all the time together. I've met some of his family and he's met some of mine. Up until recently we used to talk to eachother everyday if not in person, than on the phone. But lately he'll tell me to call him the next day after we've hung out for the night. I'll call but sometimes he won't return them now as much as he used too. We don't fight at all so that would not be the reason, and we still always do stuff together. He works full time in construction, and I'm going to school and working. Could it be that he sometimes doesn't wish to call me back just for the sake of needing his space? That's pretty much what I'm assuming, I just need some reassurance. Thanks

Yes it sounds like he needs some space. He hasn't been able to breathe since you have been together so much.
You may not feel you need any space but guys need a little space now and then. Its healthy for both people to have space and a little time apart. Just let him breathe!
Stop being so clingy and "addictive".
Needy clingy girls are a big turn off for a guy!

Has he said "i need space"? If not, then maybe he is just busy. Even in a relationship people want time to themselves. It does not mean he needs space. You guys don't fight or anything so I really don't know why he would need space. Ask him about it.
