Have you ever had to lose a friend because of a relationship?

[Gunther]

I met this girl a year ago in college and we have become amazing friends since. I started to fall for her and I care a lot about her, but shortly after meeting her, her and her ex broke up. Just recently they are starting to get back together and getting a lot closer and she is slowly talking to me less and less...

So here is the situation, she obviously is forgetting about me, and if they are going to be this close and be in a relationship soon then I guess our friendship is over? I can't text her while she is dating another guy, that isn't fair for the other guy. Even though I can't stand her ex and I think he is an idiot and treats her like crap, I still can't be texting his girlfriend all the time...

So what do I do? I don't have any social media so texting is the only way we communicate...
