Married for 7 years, no kids. 31 male.

My spouse is honestly a good woman and wife. She can be a bit lazy and boring but she's kind, doesn't nag, and is understanding.

I can't stop thinking about being single though. I badly want to sleep with other women. I want to travel more. I want more excitement and adventure. She's kinda a home body and enjoys a movie with family. I want to go get lost in a strange place and see what happens.

If I were to leave, I don't think I would ever try to re-marry. I don't think I could find a better wife than her.

My questions:

Would I regret this later and try to get back with her?

Am I overrating the single life since I've been married so long?

Is it reasonable to think I'll remain single for the next 50 years?
