You’re not ecstatic about seeing him
Did you ever end up in a long-term relationship with someone who you were not looking forward to seeing? I mean really, deeply, butterflies-in-your-stomach excited to see him again? Probably not. You should be sure you want a second date, or a tenth date. As much as you try to talk yourself into liking someone because you don’t want to be alone, if you’re not giddy about the person, it’s because your intuition knows it’s not going anywhere.
