Basically me and this girl were hanging out for like a month and then we stopped she still texts me and I would have conversation but whenever I set up a date she would be busy. So from Friday I’ve stopped reaching out to her and when she reaches out to me I keep convo short. Should I send her a happy birthday text or leave it. I haven’t seen her in a month but she did message me last on Monday were i exchanged 2-3 texts with her.
