Keeping My Mouth Shut

I feel like a complete idiot. I should've kept my mouth shut the other night. Now I'm stressing over the fact that I told him I'm in love with him and I remember him saying, "you're just confused..." And yeah, I am confused! I'm totally confused. How could I not be? I think I'm in love with my best friend/one of fiance's best friends... Ugh. Whatever. So, I've decided to just not talk to him for a while and see what happens since he's not living out of state at the moment. But its only been 24 hours since I talked to him last and if feels like forever! I am constantly thinking about him and I have to actually make an effort NOT to text him when I think of stuff that reminds me of him... or to just send him little inside jokes. I'm so ridiculous. I've really been contemplating talking this over with my mom because I know she'll be the first one to be accepting of the fact that I'm having issues. She'd want me to work them out before we go and spend thousands of dollars on a wedding for a marriage that isn't right. But at the same time, I'm just scared to talk to anyone about it because I know I'm being so unfair to my fiance. Everyone will hate me for it. It will be a disaster.
