Long Distance

So my boyfriend is going to college in August and i’m actually really scared. We see eachother at least 3 times a week, and I sleep over at his place at least once a week. I’m super attached to him and he’s my bestfriend. Of course I have other people I plan to spend time with when he’s gone but i’m really worried on how I’m going to adjust once he leaves. Does anyone have any advice on how to make a long distance relationship work? He’ll be an hour and a half away and he was planning on coming back a lot but now he doesn’t think he’ll have a car. I don’t know what to do. Ending the relationship is the last thing I want to do. We’ve already talked about our future together and we’ve been together for 2 years.
