Should I go or should I stay?

So this guy that I really like is DJing a party like 2–3 hours away and he really wants me to come. He was in a car accident recently (he’s ok) and after he told me that he loved me and that I really mean alot to him. I said that was nice and that I care for him too. I don’t love him, yet, so I didn’t want to say it. The thing is I’m on my period and I feel really bloated and icky so I really don’t want to go. I hate to be so gross but its really heavy this month and I really don’t want to have to dress up and feel paranoid about “accidents” (ladies, you know what I mean). I also have no one to go with (all my friends are “busy”) so I would be going by myself to watch him DJ. Sounds fun right? Of course not! It sounds like hell but I don’t want him to think I’m blowing him off because I don’t like him or the “love thing” has scared me because it really hasn’t. What would you do?
