Am I crazy?

I think I’m just confused more than anything.

I’ve been seeing this guy for somewhat years now. He lives in Sacramento, California and I live in Colorado. Just today he uploaded a photo of this girl on his Instagram saying exactly this.

“ Thank you Los Angles for having us, it was an amazing experience it was fun and would do it again. And a good trip with this one (her username) ❤️”

That obviously means he’s with this girl yeah? I’m just so confused because he texted me asking why I had an attitude problem when I didn’t. I told him, if you are in a relationship with anyone you need to let me know because I will stop all communication with you. And he claims that it was a “business trip”

I just want guys to be honest with me.

Tell me what you lot think...

What do I do
