Distance Relationship

.....i feel horrible just writing this...ok me and my boyfriend been together 4 years going on 5. I love him with all my heart mind and soul. but he lives like 1 45 mins away from university and I get to see him maybe once a week. I feel like every time we are away from each other our love isn't as strong as it is when we saw each other everyday. Like I Love This Man To The End Of The World...What do I do? How Do I Bring It Up To Him?
