We've been together for 15 months now, so it's not a new relationship.
I don't really know how to handle this, it's not the first time he doesn't answer, so it frustrates me, but I haven't really said anything, because I don't want to be the annoying and nagging GF.
I've chosen that I wouldn't text him, until he would, but this is starting to annoy me.
So I'm asking, what I should do in this situation?
And thank you for any kind of help, and that you gave the time to read.
