Is he not interested or am I too clingy?

Molly
In a way I don't think I'm clingy at all but I feel he may think I am. When I see him in person we're super loved-up and so comfortable and silly around eachother, he takes care of me and says little things that make my whole day. But as soon as I leave we hardly speak on the phone or even text. We probably send in total 3 messages between us the whole week until I see him again. This doesn't seem to bother him but it really grates on me. I understand he might be busy sometimes but surely he can take 30 seconds out of his whole week to ask how my day was or something. Opinions?
