I meet my girlfriend once, maybe twice a week. On other days, I try to message her and send flirty comments, things like "love you" and the like. On days when we've just met up, she will reply straight away with other comments, often more flirty than mine! However, on other days, she never replies at all. I can see from app that she's read them, but never get a reply. Is this a sign that she's not interested any more? Of the two of us, she is the more outgoing one so would expect her to say something if she wanted end. She is also more friendly with other guys recently. Do you think it would be unreasonable for me to end relationship over this?
