Need some sincere advice

Ok let me reiterate. I didn’t blow up on her at work. I just went in and quietly told her how I feel about it. Ether way I got my point across.

And I don’t ever TELL her what to do. I tell her how it would make me feel, if she did do it. It’s up to her at that point. Same with this, until I saw that convo. Now she is not going to talk to him if she values this relationship. I like to think we have a serious thing going on. We have even talked about an apartment in the fall. And IMO there is no room for a guy like that in her life, if she wants to be with me. But again, its up to her.
