I feel alone.

My boyfriend and I have been dating for going on seven years from 15-22 years old. We are long distance and are suppose to get a place. As time goes on, I notice he gets less affectionate, he never has been super affectionate but has never been just not at all. I spoke to him about it and he says just because he’s not loving all the time doesn’t mean he treats me bad which I never said, I have said I get affection is not his thing but some would be nice. The remaining time we have until we see each other again is every hard especially when I feel alone from zero affection. Any opinions on what I can do?
