SUBREDDIT: r/relationship_advice
TITLE: I'm going to blow my 10 years relationship away by telling the truth to my partner. Any advices ?
POST: **The Background**: 36 Yo Male redditor here. I've always been into girls. I've always see them as potential partner. I've always heated on pretty much every girls I've met for my whole life, yet, I believe i'm pretty good at reading signs and I stop before it becomes annoying (for the ladies or for my friends) (read : I strongly believe i'm not an asshole, but you decide)

I love the sensation of being usefull and providing emotional comfort to a woman and I try to leave my partners better and more secure than before I met them.

One day I met this girl who fell totally, unconditionally in love with me.

I was at a point in my life where I thought being into a committed relationship could cure the vast sentiment of loneliness I've always felt. And it worked in a way. Her unconditional love provides me security and confidence in life. We build things together (we have a daughter), and I feel useful securing her in almost every aspect of life.

**The story** : routine is now installed (almost 10 years together). I crave flirting (and fucking.. a little). I've been feeling miserable for almost 2 years. I can't stand it anymore.

So basically I have three choices :

* be miserable

* cheat on her and be miserable

* tell her everything and potentially lose her, destroy everything we've built, leaving my daughter with a distant father, and an depressive mother (also, be miserable).

Voila. I'm planning to tell it all quite soon.

Hopefully you have advices or similar stories.
TL;DR: 
36 yo male. In a relationship but can't stop flirting. Thought I would grow up but was wrong. Feeling miserable
