I need some advice...

My boyfriend and I have been together for a little over 7 months now and I’ve grown super attached to him. We don’t live together, but I see him every day after work to eat dinner and hang out. This whole week starting today he has an event that his work is sponsoring that he needs to attend so I won’t really get to see him at all and I feel super sad. I miss him already and I know being this attached is not a good thing for either of us but I don’t know what to do. Any advice would be greatly appreciated.
