You know. I was that guy to a degree in a relationship. Lemme explain what happened.

I was fine with her having guy friends. But I also wanted to get to know them so I, you know, knew them. She was cool with that to an extent. She had a bunch of guy friends, and I met most of them, but some of them were seemingly off limits. And she was constantly texting whomever...names I didn't know.

So then I felt like a jealous idiot when I'd eventually have to ask about these dudes I never met. Always a coworker, or friend of a friend who was hooking her up with something or other (pot, furniture, etc).

She knew this made me uncomfortable, but disregarded my feelings on this. This made me increasingly more resentful, and jealous, and just generally angry. I never kept anything or anyone from her, so why shouldn't she do that same for me?

She planted the seeds of distrust.

Fast forward about two years. We're really having relationship problems. I'm giving it all I have, and telling myself that I'm imagining things. She puts a lock screen on her phone because she suspects I'm snooping through her texts (which I am). Growing increasingly bitter, and just angry about the whole situation.

We get into one of our many blowout fights (and for the record, I hate arguments - she gets really personal immediately and says shit to me that I wouldn't say to my enemies. The rage runs deep with this girl). She disappears, and doesn't come home until the next day. Tells me she got wasted with one of her friends and crashed at her friends place.

Nah. That's a lie.

While she's in the shower I go into her phone. More texts from her "coworker" (who she's constantly texting and snapchatting with). Basically a conversation about how much fun they had last night and making plans to do it again. To her credit, she didn't respond to some of the nasty shit he had said to her.

I go nuclear. In lieu of doing something to end up in jail, I leave the house. All of my trust issues with her have been confirmed. Everything I was worried about was absolutely true. I'm completely vindicated, and completely destroyed.

Lessons learned the very hard way.

So my pieces of advice to you on how to approach this:

1. Boyfriends get jealous of other guys (girlfriends get jealous of other girls). That is a fact. If you don't want boyfriend to be jealous of other guys - be very transparent.
2. If you care about boyfriend, introduce him to your other guy friends. This shows everyone involved that nobody has anything to worry about.
3. If boyfriend can't get over it, then maybe you shouldn't have the type of boyfriend who can't get over it. You know, maybe that boyfriend isn't the boyfriend for you.
4. Have some respect, and don't cheat. If you think you might, you better be ready to end it before shit goes down.

For the record, that relationship ended (big surprise) and I ended up meeting someone who is infinitely better for me. It broke my heart, but I'm a better person for having went through hell. Sometimes people aren't meant to be together, and that's okay.
