relationship advice needed

my fiance and I will be getting married in about a month. she's the love of my life and sometimes I wake up crying in the middle of night when i have bad dreams about losing her. its okay though because I usually just sob on her shoulder until the feeling goes away. she doesn't mind though because she's usually up late on her phone anyhow.

I've noticed she's been snapchatting with a friend of hers a lot lately. it's this guy named Chad. he's a pretty cool guy. he works out a lot and lifts a lot of weights. they've known each other for years, and he's single but I'm not threatened by him (she told me how she thinks he's gay haha).

anyhow, so i'm staying at home for my bachelor party in a few weeks. I'm the dungeon-master for our D&D group, so we're going to have an epic game (+2 to all attacks if you dress up!) and we might order some pizzas and stuff too I'm not sure yet I'm not sure if i can fit it in my macros.

she told me she was going to hang out with Chad the day before, and that she probably wouldn't have good phone service and that I wouldn't be able to reach her and that it'd be late before she was able to call me back. that's okay with me though cause I can just text her and tell her how much i love her and miss her and she'll get the texts later

but I also thought I could surprise her though and go by to say hi to them both later that evening- I could bring them some of the left-over pizza (if there is any left over lol).

what do you guys think? should I go over there and surprise her or just let her have her time alone?
